Hhhhhhhmmmmmmmmm. You set a boundary, and she ignored it. So you think you trouble is that she lied, but you'd be wrong. The trouble is that she now knows that your boundaries are flexible. She now thinks that it doesn't matter what your rules are, she can get away with doing what she wants.

When a woman is playing the jealousy thing on you (they all do) you need to respond by withdrawing the things that she likes, like cuddles or time with you. The minute she starts with that shit (She will) you need to withdraw, become busy with work, and then spend time going out with your buddies. You need to condition her that if she wants nice times with you, she will have to behave nicely.

Now you have an issue. She is not only getting what she wants out of her jealousy provocations (your mateguarding), she now knows your boundaries are all bluff.

You tell me, what should you do?

Cancel the date tonight, say you're busy with some stuff. Withdraw attention slowly. Don't call anything out beta billy, never mention it.

Dig her guts out harder and better and game other hoe's immediately.

First off, she is slavic, therefore she is not 3rd world, but 6th world and a MASSIVE HIDDEN HOE.

Any woman that "escapes" to the Western hemisphere is a hidden slut. Slavic/Southern & Eastern European women are known for this man.

Just go to any bar/party in western europe and the only girls open to gangbangs and DPs that night, only if you don't tell, are slavic chicks.

You never, ever, ever date/marry/LTR a 3rd world woman. You might as well stay single for the rest of your life than believe the fairytale that a slavic woman presents to a man. They are very smart and therefore are horendously foxy and evil.

In regards to your situation, they are 100% already fucking, you're just the nice mattress she gets home to. Never tell her, use her and always, but always game other women, even if in an LTR, secretly. Your sexual entity on Earth should never be locked down by one single woman.

The fact that a woman knows and sees that you can get laid easily, even if she is your wife, it's your most important weapon, more important than your money, looks and even your own life.

At this point I'm debating whether to call her out and withdraw attention or just withdraw attention without her knowing that I know she lied.

Demote to FWB.

since she came from Ukraine

you're fucked. it's only a matter of time before toxic american women pollute her mind and consume her entirely.

They are fucking, and you're the safety net and her escape plan from the shithole, it's all about the papers.

You did everything wrong and calling her out won't accomplish anything but her gaslighting you and playing the victim card.

Demote to plate, 3 months is a joke.

just withdraw attention without her knowing that I know she lied.

This. Never tell a ho how to get better at being a ho. Never tell them how you caught them. Never tell them that they demoted themselves fucktoy-only-forever.

You just enact the consequences, and it is not up for discussion/debate/closure/whatever bloopy bullshit rationalization that will just end up with her reassigning blame onto you and/or getting better at being a lying ho.

Demonstrate, don't explicate.

Do not call her out so she can learn from her previous mistakes to perfect fooling you and guys like you in the future. Guys like you are the reason many females think men are idiots. You seem like someone with above average intelligence generally but when it comes to her, she makes you look retarded. To begin with, she is from Ukraine and is overly eager to get into a relationship and eventually quickly start a family with you, a Canadian citizen, yet you see nothing suspicious; as someone else said earlier, you are her citizenship papers. Secondly, I'm 95% sure they already had sex. if she really wasn't interested in this man, why even mention him? If a fat, unattractive co-worker routinely tried to get your attention would you tell your "girlfriend"? Exactly. Just like how a boxer in the beginning of a match will throw out light jabs to test his opponent's reflexes, assess his defense & movements, and gauge his reach, your "girlfriend" repeatedly brought him up to gauge how you would respond and your boundaries. You've shown that your boundaries are worthless. This is important because, if you decide to stay with her she will know how to lie and how to assess your behavior and awareness by how you fumbled this. Know she is getting smashed by him and will utterly destroy you if you get serious with her
