She did this out of the blue to you, but this process started some time ago in her head, that's how it always works. You probably just didn't notice the change in her behavior.

Look into Briffault's law. https://www.stickmanbangkok.com/readers-submissions/2009/11/the-rosetta-stone-of-womens-behavior/

Women are not investments and cannot be treated as such. Unless you invest in something highly volatile, it won't just disappear in a moments notice.

It's also very likely whatever she has with this guy has been going on for a while now and she's already fucked him.

How does one earn 73k a year? ????

There are many great comments in this thread already so the only thing that I can contribute is this:

Never forget that pain. Never forget that anger. Safe it. Deep inside you. This is your inner fire for your furnace. Use it to hammer yourself into the man that you want to be.

There will be nice and soft times again. You will get lazy again. And you will get complacent again. But it's monday 6 o'clock in the morning, it's cold outside and your ankles hurt from yesterdays workout. And you remember. And you'll go lift.

You can’t explain it? TRP is basically explaining this 24/7.

So once again: men and women are different, their sexual strategies are different. Women are wired to feel desire for the highest SMV guy in the room, no matter your history with her, no matter what you did for her, no matter how she was feeling yesterday.

You know it in theory but you haven’t integrated it, or you forgot it.

What happened is that this relationship bliss made you lower your guard and revert to the lazy blue pill thinking of type “hey she’s great and the relationship is doing good, there is no reason on earth for her to break up”. But hypergamy doesn’t care about reasons at all! She met a better guy than you, the tingles got generated, she switched. Female sexual strategy 101

She's had feelings for this guy for a while and she wouldn't just leave you for another guy unless they had already slept together. This wont necessarily make it better, but she's been cheating on your without your knowledge. If the roles where reverse she could get revenge on you in one of many ways, as a men the best you can do is walk away cleanly.

​

The guy is unfortunately higher SMV than you (at least to her). You can either work to increase your SMV or just go for lower SMV girls who can't do better.

​

It absolutely sucks, but this is why the advice is to not let yourself fall into this trap, women branch swing which is exactly what she did.

LTR of 4yrs who had a dozen green flags

I have said it before, I will say it again: green flags do not exist.

ZERO WARNING FROM ANY OF HER ACTIONS.

In the weeks to come, as your brain processes everything, I think you will find a bunch of them. You were blind with complacency.

This is one of them:

rarely shit tested me

We lived together for 1 year

Loss of mystery/dread + Too much comfort

Recipe for loss of tingles in LTR

Read sidebar and move on to better things

This was brutal to read

Your turn was up, now it’s someone elses turn.

You can do everything right and still have things go wrong. That's life.

Doesn't matter how many green flags she has. All the matters is that the single red flag. There was a build up to this event.

If she breathes, she a thot. Sorry bud

Just don't say yes to getting back together.

Fam. This fucking feeling. NEVER FORGET IT. This is a cold branch swing in action. Learn from it and you will become bigger and better. This is the red pill men find hardest to swallow:

Women do not love the same way men do. A womans love is even more unconditional than a mans can ever be. A womans love is fleeting. A woman loves how u make her feel and how much you make her feel like she has secured a high value man who gives her attention (validation) through this.

The moment that ends, the tingles stop, or she fonds someone who gives it to her more(she perceive as higher value) it is gone.

Somewhere along the line you became her beta. It may have been slow. You never noticed. You stopped gaming her. Sadly, even in a ltr with a good woman we can NEVER stop gaming them. Its a commitment for the entire lofe of the relationship.

She was cheating way before she said those words. Or she's very honest and did what a man should do. What's more likely?

Her “spending time alone” through the week was her romancing with new dude

You got comfortable and likely didn't see warning signs. Lesson learned to be vigilant and not complacent.

That's pretty fucking infuriating. Lay off the drink though, tone it down. Get tested for STD's too because she was cheating.

edit: bring a girl home and fuck her in your bed while your ex is there

The hardest part hasn’t come yet. When she realizes the enormity of what she’s done. When she realizes that what she liked about him was the fact that he only needed to play one role (new excitement while her security needs were already met by you) and shit is real now and he has to fulfill all roles and will leave her unfulfilled she will try to come crawling back. Relationships with affair partners have a 90+% fail rate because of this reason... the relationship isn’t as fun when it’s no longer butterflies and being “bad.” You gotta be strong and squash that shit and tell her live with her choices and to have a nice life. While you become the best physical, financial, and social version of yourself.

Also, if she contacts you again, ignore. She doesn't exist in your world anymore. N go bang other girls right now

All of you guys are scolding OP for not being RP enough.

We are all human and we develop feelings for the people close to us. You're not going to be some macho, emotion free robot just by lifting and holding frame.

I think he just wants some sympathy from us rather than being told he didn't read the side bar.

Your relationship was comfortable, like an old shoe. It sounded like there was minimal passion in between the sex sessions too, at least from the robotic way you described everything, like you were friends than lovers, maybe I'm wrong here and it's just your shock talking.

But I think she was bored.

4 years is also a long time for a woman in her prime not to get knocked up, biologically and evolutionary speaking. It's something that we men like to ignore, but female bodies are already ready to get pregnant at 13-14, and by their mid-20s a childless woman will have spent the better, healthier half their reproductive life fucking with no results to show for it. They may take the pill and all, but their bodies are evolutionarily designed to procreate, not for modern society, careers, and all that unimportant bullshit. If one partner ain't getting the job done, their biologically program is gonna signal them to jump to another, no fucking strategy will prevent that.

That's why I think of these fantasies of childless ltrs are mostly unattainable. Her biology ain't gonna give a shit if you need 10 years to build a business or career while her clock is ticking away.

4 years?

The boredom hit. You never purposed. She figured out this is her last chance to Make a big life change. The guy at work is a better match/hotter.q You just aren't what she see herself with in ten years/wants kids with. She didn't shit test you... You were roommates. Lots of reasons.

"She was never yours. It was only your turn."

First off, that little fuck fling she has at work for the co worker will diminish due to she's see the dude 24/7, and soon he's no mystery.. 80% of work couples end up not working and 1 person ends up leaving or transfer out of the company..

But all this isn't going to make you feel better. The absolutely best thing to do is go ghost on her but only until she hits you up. And when you do have her talk, make the conversation like she's a neighbor (no personal information exchange). 100% cut all ties.. Delete all her family friends off Facebook etc.. And if she never comes back, it actually tells something about the relationship (it was really shit)

I'm sorry to ask, but is there something you're leaving out? Do you not have an alpha mindset (you cry, and whine a lot?)

Even if the TRP she was bound to bounce if ever a guy with higher SMV is around but I wouldn't doubt there's more to this story

Everybody's making all kinds of assumptions and giving you "advice" based on shit they're making up.

It's okay to be hurt, and it's okay to have feelings for women. Don't let this fuck your head up in the future.

If it were me, I'd be upset there wasn't a fight. I would feel like I deserved answers, maybe you feel the same.

I know this won't sound good now, but we've all been dumped pretty hard before, and we've all gotten back on the horse and crushed it, you will too in time.

One day you'll be with a hotter girl and think back on this and be glad it happened.

Also, quitting drinking a few months ago was the single most powerful improvement to my game. Alcohol is a depressant, saps gains, ruins confidence ( liquid courage is bullshit), and overall a complete disadvantage to your game.

She at least has enough respect for you to not cheat but break up with you first. You dodged a bullet.

​

Basically, just bang 10 girls. She just gave you that opportunity.

Like literally none

like everything was great

like, like, like, like

Maybe she didn't respect you because you talk like a valley girl?

Daaamn that was ice cold brother! I am sorry to hear that you experienced that. If you don’t mind me asking, in which country do you live?

I live in Scandinavia and I heard multiple stories of man being dropped like nothing for the next guy.

AWALT. You got to see feminine nature at play in its purest form. You should get used to this. It's natural. You could spend years with a girl and share "love" and she'll hamster everything away like it was nothing. That's life.

You'll be fine bro. Eventually. I went exactly through the same thing in college.

You've said how great she was to you.

What did you do for her?

AWALT. u/321cmecum you had your turn. A four year long one at that. She didn't leave you; you dodged a bullet. After you're done binging, hit the gym heavy, and get those feel good endorphins pumping. You'll be back to gold in no time!

Godspeed and good luck!

You were a beta cock fag and failed to give we pussy the tingles.

End of story.

Also never ltr while under the age of 30z

That must suck. I can't really give advice based on what you're saying. It just seems a tad unprofessional of her to date someone from work.

Unfortunately this beautiful relationship is incongruent with raw sexual desire. LTR’s are for stability and companionship which kills intrigue and excitement. I feel bad for you because it seems you had your shit together and were redpilled from an SMV standpoint in your relationship but whether it’s a guy with higher SMV or simply the intrigue of the unknown and thrill that comes with a novel guy, which never goes away, a woman will not stay unless she can’t do better or there’s constant dread that you can and might do better. Sexual attraction for women is stimulated by jealousy, insecurity, fear of missing out and hypergamy. Now you might have the last but sadly, and it’ll always bother me, the stable, loving and trustworthy committed relationship isn’t compatible with long term sexual desire. It needs chaos, drama and unpredictability to keep women addicted to the same dick for decades and that’s not a “good relationship”. If you want a good long term situation for your life, better to spin plates into your late 30s and marry a woman at her early thirties wall when her SMV is declining and yours is still rising.

Read the side bar

AWALT, who cares. Move on.

One thing: hypergamy doesn't care. She found someone who she perceives is better than you and left you for him.

Don't beat yourself up over this my man. No matter how shitty you feel now, things will get better. Don't give up on yourself and keep improving yourself even if you just wanna lay in bed and feel sorry for yourself.

appears like you have really nothing to offer her. seems like she just takes care of you all the time, especially when you're sick (also a sign of weakness). tingles come easy for them in this kind of scenario.

You were her safe beta bux whilst she fucked chads at her own will. This guy was not the first.

So she’s still at your house then..? Pick up a girl and fuck her in your bed.

Told you to sleep on the sofa the disrespect does not stop

She’s been doing this for a while. Women are masters of deception, it’s part of their DNA. Thinking back, did she ever act out of the ordinary - different gym nights, hanging with her best friends more often, coming home later (even 1/2 hr), etc? She’s been doing this for a long time. Hypergamy is ruthless.

She’s not yours, it’s just your turn. The glass is already broken.

Quit drinking, get your ass back into the gym, take some time to mourn the loss of your relationship, do the Monk Mode thing for a few month to clean up your mind.

The only green flag I see is that she isn’t your problem anymore.

Shit situation that you handled reasonably well at the very end.

You can sleep on the couch and ill help you pa k is a fucking great response.

Now where you went wrong is the lead up too this.

Seeing green flags is complacency incarnate. There are no green flags for creatures as prone to whimsy and illogical behaviour as women in relationships are. There is only the absence of red flags which can change quicker than I can say "I told you so."

Somewhere along the line you lost something, It could have been the air of mystery, your backbone or just your drive to be better. Something changed that lowered her attraction enough to set her down the path to window shopping and eventually full on branch swinging. Identify that change and avoid such things in future.

As others have said, with a clear head you'll start seeing things in a new light and have a few revelations about signs you missed.

As for right now you need to get your head back in the game. In a situation like this drinking is poor form but understandable. You need to give yourself one night to be a pussy and drink your sorrows away. Next morning no matter how shitty you feel you get the fuck up, tidy your place and yourself up and do something productive. Whether that's a fucking dire hungover gym sesh or fully removing any of her influence on your place just do it and then lay off the booze until your minds right son.

DO NOT wallow in self pity, do not let it fuck your routine. If you need to think go do some fucking cardio son. Nothing like a long run, ride or swim to mull shit over. Otherwise eyes and mind fully on whatever your mission is.

pulled away and said to her "You can sleep on the sofa. Also delete my number and begin packing your stuff up, I'll help to speed things up".

from the emotion in your post I highly doubt you were this calm and accepting immediately.

That is harsh, but allot of harsh truths in the replies also.

The one saying that I live by from this site....

She is not yours, it's just your turn....

And for you mate, your turn is up. Always enjoy the here and now with a woman, but ALWAYS, be ready for it to end. Always. It's just how things are, as much as we don't like it. Hypergamy is what it is, AWALT. There will always be the risk of a guy with higher SMV than you. Specially in corporate. And don't live with women.

Dude I'm sorry this happened to you. Had a similiar thing where there were no red flags then outta nowhere she decides to find a job out of town and end things like a robot. Like now I find it hard to trust these chicks when they are all happy and saying "you are their world" and then suddenly they go beep bop boop we are done.

Ok, I know you’re getting a ton of replies so I’ll try to make mine short & direct.

My first thought as I read this was that she got bored. You look good on paper but women, especially young women, care about the tingles you give them.

You said she rarely shit tested you. This leans towards confirming her boredom. Women like feeling the highs & lows, like a roller coaster, of the emotional spectrum.

Also, try to take some time to properly get over this girl. Process what has happened, learn to accept it & MOST OF ALL - grow from it. I know this stuff is painful & it shakes you right down to the core. But I promise you, it’s like the diamond in the rough analogy, this can make you stronger, better & more of a complete man.

Last thing I’ll say, I’ve lived with girls before & it never worked out. Only when my last girlfriend got pregnant, did I allow her to move into my house. We lived together a year or so & we got pregnant again. So I had two kids before I married my wife. I think it works (us living together) now because we have kids together & I’m a lot more mature. There’s something about living together that makes it feel like friends sharing an apartment together. I highly suggest not doing it.

I wish my LTR did that. You have a great opportunity ahead of you to work on yourself in peace.

Never again live with a female.

Hey man I'm sorry that happened to you. It's happened to almost all of us here I'm sure. It's the worst fucking feeling in the world. You're going to be fine and will be a stronger person from this

Dude it sucks, but take a 2 week trip to thailand, experience some.abundance, and I promise you won't be able to remember her name when you get back

That was just your turn

Wait homie. What was her explanation?

this is cold hard truth they will always branch swing if given the chance and your LTR did... god speed and happy hunting

All sounds to good to be true. Too much comfort and the dreaded move in. Especially these 8/10 "angels" need a lot of dread to keep them interested, even if they not make it seem like they do. Some fighting, dread game and lots of bratty little sister play is what keeps the flame going. Otherwise the fire will burn out and only burn again for another, stronger, man.

We have all been there. You are going to be fine. You are a bit young for an LTR, but that is beside the point.

​

This is why red pill encourages an abundance mentality. When this type of thing happens, you stoically gnash your teeth for a bit and say "dang, i hate when that happens" and you move on to the next one. You have abundance mentality and you "know" you can get with another girl in a reasonable amount time at your own pace.

​

she never loved you the way that you think. women love and invest differently. she won't love the next guy romantically either. all women love opportunistically, not romatically.

​

Now is a good time to read The Rational Male by Rollo Tomassi. It covers just about everything. You will keep busy for a bit, regroup, and reading it will be investing in your future.

​

Your going to be fine. As Uncle Vasiliy would say, "go associate with ten other women"

​

​

You showed weakness in the hospital and opening up to her. Once women see weakness they lose interest.

Let go.

Humans are like little bald monkeys. On a wet rock in space. We live for maybe 100 spins around our star, out of billions.

Further, relationships aren't a collection of things you keep. They're things that are happening or aren't.

So decide to let yourself take a little while to let yourself mourn, and then move on.

Welcome to young adulthood and hearbreak! Your depression doesn't need explaining: you're heartbroken. Oxytocin, dopamine, and more feel good chemicals that you've come to rely on from your relationship are leaving your body. The good news is that breaking up gets easier with practice. Expect about four months of emotional recovery.

Cut down/moderate/quit the drinking quickly, preferably by the time you have to work on Monday. It will only delay pain and the mourning process. It will also fuck with your brain chemistry and teach you that drugs can replace human connection, which is a lie. I empathize with your desire to do so, but it is destructive so knock it off ASAP. If you do drink, drink socially with friends. Also, replace drinking with lifting.

In the future, don't cohabitate with your partner. She was not the one. There is no such thing as the one. Find some other bitches. I am genuinely sorry for you, but you'll do fine. Use this as a chance to upgrade and enjoy variety. Keep your finances in order, keep up with hobbies, and if you can extract the remainder of rent from your ex, get that check.

Not gonna lie this will hit you pretty hard. There's a lot of points in there that look like you've set yourself up for this to take an emotional toll but here's a few key points to help you through:

-Being on trp will help you make sense of so much of this, so you're already off to a decent start.

-Make sure you have 0 contact with your ex. No stalking her social media, probably distance yourself from any mutual friends, block her number, get rid of anything that is gonna make you think about her. Do not make any excuses for her or kid yourself that you can fix this.

-Don't dwell on the green flags, all that means is you had a higher smv than her. She can still leave you for someone that (seemingly) has a higher smv than you. All you can really do about this is increase your own smv. In future I would also probably not aim for anyone with a much lower smv than yourself. It doesn't really protect you as much as you might think, you're better off making your own smv seem higher than it is or just genuinely jacking it up. If you're making $73K per year you've definitely got enough to work with, especially now you have one less expense.

-She was definitely cheating on you. This is also a topic you probably don't need to know any more about than you already do.

-This would probably be a good time to go into monk mode, just make sure you don't spend more time than you have to thinking about what happened. But if you can throw yourself into training, investing, self improvement etc. for the next six months you'll be able to put yourself on the next level.

Look after yourself and good luck!

Props to you for making 73k/year at 24. Sounds like you’re on top of the world (other than this relationship). You’ll do fine.

So, first, the guys saying she was cheating on you for a while are 100% correct. Monkeys don't let go of the old branch until they have a grip on the new branch.

She had no orbiters I knew of, good friends from work (professional office environment)

Well, there was at least one.

and no IG or selfies.

That you knew about.

Like literally none.

You keep using that word, "none". I don't think it means what you think it means.

Depressed as fuck and can't explain it.

Because your Reptilian Brain is thinking, "FUCK! NOW where am I gonna get pussy from?!" Maintaining abundance is hard. Competing is hard. That's how old married guys getting divorced by their wives sometimes wind up as the back half of a murder-suicide.

Not gonna lie I am drinking pretty heavily too. People are fucking weird.

Cut that shit out right now. It's not helping anything. Channel your hurt into positive things. Use your free time constructively.

Oh, and GFTOW.

AAAnnnnddd bang! There goes the blue pill balloon.

It's shit like this that I think about when women ask me 'why aren't you committed'? Go fuck yourself, that's why.

Bitch probably went into total self-centered mode, arranged everything for a while in order to ensure the branch swing would work.

Anyway, she's putting herself in a fucked up position. If it IS a guy from work, and she's moving in with him, then she's shitting where she eats and will also be in a live-in situation with new guy. Unless he knows Red Pill on hard mode, that situation isn't going to go well.

With how bad a decision it is, I wonder if it is really is a 'guy from work'.

​

A few things stick out to me:

You said you were in the hospital with an autoimmune disorder. It’s possible this made you look weak. She might have felt like your genes were not worthy of mixing with hers.

Also you stated that you often spent time apart during the week. This is a red flag to me. Your woman should be borderline obsessed with you and always want to hang out with you. The fact that this wasn’t the case should’ve been an indication of her lackluster attraction for you.

Finally, all those good qualities you noted about her made her sound equal to or possibly higher than you in SMV. The guy she’s been fucking from her work is undoubtedly better at sex and might also make more money. She upgraded and thus felt no guilt for leaving you because she’s succeeding as a woman.

Best of luck man, I wish everything get better for you. This sucks so bad.

Just adding to what everyone else is saying. What happened to you is that your girlfriend fell for her work husband

It's a thing.

I feel you man. Something similar happened with me, although I had prior warnings which I ignored thanks to oneitis. Check my post history, my last post on TRP is my story and there's some pretty dope advice there. Stay strong. Keep lifting.

Been there my guy, check my post history.

Ghost this chick, talk this shit out with people close to you and vent as much as you need to, and then find out where you can improve and work on that while cultivating other female options ASAP even if its just hanging out and chilling. You have to get the abundance mindset rolling or you will stagnate.

Better 4 than 10. Better LTR than wife. Better in 20s than 30s. Better with no kids. Hypergamy does not care. You can do everything right and people (women especially) can still let you down. It's all new so I'd imagine you'll go through some emotional loss. Stay strong bro

I will let you in a bit of a secret, You're blind bro.

Their were red flags all over the place, you just ignored them. Shit like that doesn't happen out of nowhere, count yourself lucky and walk away.

​

There must be some red flags definitely. You'll realize them as time passes. Think of it objectively. Definitely it does feel bad but it's just part of life. As red pill mentions about monkey branching and awalt. You'll soon realise the mistakes. And also she might come back to you if things don't work out with the new guy. That is the time when u have to stand up for yourself and not entertain her in any way.

Sucks to go though this dude. It sounds like when you two got together you isolated yourself from all plates and potential plates (as you are depressed from loosing one.) Moving forward remember this pain and try not to do this again? She clearly had other options and took one of them. In her mind at least.

I bet she was cheating on you. Dont let her sleep on your couch it will make it harder for you. Just kick her out really quick. What a bitch

Mate people are weird. Chicks get you to come out at night when you're just settling in for a good night at home then they leave you but call in the morning to check up on you to save face or some shit. Girls will be talking to you out and they have their bf right there, the girls don't give a crap. If he wasn't there she'd be in your pants. Or they go out with you one week then the next they're back with their husband/ex trying to "work through" shit.

My advice is don't settle into a relationship and if you do don't get comfortable. You're young so you have not wasted any time, really. 4 years, was good but move on. You handled this well. Don't let it get to you. Bitches be bitches.

She checked out in her head probably 1 year ago then went through the motions because of what you had. Let her go because that girl you liked for 3 years is gone. It's just the nature of the world. You can't fully trust anyone anymore but don't let it wreck being open enough to people going forward and after a time. Girls have so many options these days, it's disgusting. The best advice is don't let it get to you. She's not worth it. All the thinking you're doing about it is not worth it either.

You've dodged a bullet. Yes she is probably an idiot but remember she'll do that to him one day. So maybe he's an idiot. You got her best years, that's good. Next time don't let your girl move in, only after 5 years consider it. You're in your 20s you have plenty of living left to do. Sucks now but it won't when you're 30 for example. You'll stop caring about this in no time. You've been saved even bigger trouble from her.

Well she's probably cheated on you too. I wouldn't let a cheater sleep on my couch. Throw her shit out.

Hey dude, commented earlier. Just wanna say ignore all the blunt tone deaf comments from guys who can’t empathize that this was disorienting af for you and it’s impossible to not let it churn in your head. It reflects poorly on them any guy that can keep an LTR for 5 years with a chick who works out has plenty to show for himself.

Hypergamy, War Brides theory, female nature, AWALT.

Btw, never live with a female unless you’re married.

Pretty sure she already cheated on you and you've probably lost frame with her and she decided to branch swing

Gurls dont need a lot of reasons to cheat, I'm willing to bet that the guy is not even on a higher SMV than you are but its just the way it is

You might have been "too loyal" to her and your dread game is weak

Anyway although it might be hard right now coz you already caught feelings for her but the best thing you can do is ghosting her and work on yourself and your game

Your mind will try to trick you to get better and raise your SMV so that she might see this and come back running to you but believe me this is a really toxic idea and you should erase this idea completely and forget about this girl for good

Make sure you protect any belongings while she is leaving. Sounds like a level-headed breakup, but you can never be too careful. Store valuables elsewhere, maintain a watchful eye, get her key.

You don't own people, and you can rely on people that are weaker than you... that's a general rule in life, try to remember it next time.

That must suck. I can't really give advice based on what you're saying. It just seems a tad unprofessional of her to date someone from work.

I just want to give a quick bit of advice. You have to not focus on her or her actions, focus on your life and what you want. Your brain, dick and emotions will fuck you up, if you let it. I know. I had my wife of 5 years walk out on me and take our kid with virtually no warning. She told me in the morning and when I came home from work, she and her brother had taken all of her stuff from our place and my kid. It fucked me up for years. Don't focus on why she did it, it will destroy your soul.

​

I'm almost fifty and it took me a long time to realize. She was just a stupid person who followed some temporary tingle fest. The guy she left me for dumped her and she had a shit time for ten years. She married some schlub who looks like her dad and made zero money (although she had a fair bit of mine thanks to child support).

​

Don't dwell. Move on. They do.

I am no way trying to compare my shit to yours. But it's just a reminder of how women "love" and how these can serve as teachable moments. They can literally overwrite you like a hard disk. I met this chick a while back and I caught really bad oneitis. I thought things were going really really good. One day she just blocked me. A few days later she unblocks me and tells she wants to be with some dude who is buying her a house. Then she blocks me again. That's the short version. It was legitimately sociopathic. It has been 4 years since I had considered the idea of dating and this was the result. It's been over a month and that shit is still stinging me. This person has literally been apart of your life for 4 years. I can't imagine. I just want to say it seems to be apart of their nature and like most guys who come here, hopefully you can take solace in that you aren't alone dude.

Do not ever live with a LTR unless you are married. That is the lesson one has to take out of this.

Is she on birth control. I'll put $50 on it she is.

I agree with the other commenters that this started some time ago and she has already slept with this guy. Many times, the girl will be a total bitch leading up to this and do things like start dumb fights over nothing and put a negative slant on happy times or events you shared. Here, however, it sounds like she was much more overt. When your head is clear, you'll recollect things out of the ordinary that she did in the past few months. Make a note of them for the future, and dump the girl when you again see that behavior repeated.

I understand the heavy drinking, but it's not going to help. Just don't do anything stupid and whatever you do, don't contact her. Delete her number and remove and block her on social media. And don't get drunk in public or go out anywhere drunk.

she can be an angel but will drop you at a moment's notice if a better option comes along

stay strong brother
