OP, I'm guilty myself of taking back chicks, but I have learnt to do it gradually instead of just breaking

also I was not worried about dumping, but if you deal with 1 plate sometime you can slide into allowing too much

block here everywhere and contact only when want to see her so u wont see any other message in the meantime if you suspect being too invested

remember all is down to fine detail that noone here knows

I've come down on my wife a few times. If she was in charge she'd sit around all day watching soap operas and eating bon-bons while the kids become brats with rotten teeth and the house falls apart and stinks of trash and rotten food.

Is it bad or seen as weakness to communicate with your LTR things that you don’t like that she does?

It's good.

"I don't like X, stop doing it".

I recently caught the LTR in a lie and broke things off immediately and cut contact. She came back and I decided to give it another shot but told her she is gone if she gives me reason not to trust her anymore.

Good.

For example my LTR may not have the best social skills and afraid of rejection/shy. I know she holds back reaching out most of the time and showing affection in ways.

Or she's lazy.

I hate feeling the relationship is one sided in those aspects and let her know that. She mentioned that she is afraid to bother me because I am always busy/on my purpose and the timid part is from trauma from an “abusive relationship”.

This is complete bullshit, this is a smokescreen for being timid/lazy/fearful but unfortunately it translates into you doing all the work. Gradually she will take you for granted. Her actions are lazy, gradually she will lose attraction to you because you're doing all the effort and she's just cruising along. You won't even spot when she checks out of the relationship because she's already being passive now.

Was it bad to communicate this, I’m not afraid to leave a relationship I don’t like anymore but at the same time I feel like she can’t read my mind.

Here's the problem:

NOTHING WILL CHANGE.

You don't communicate with women logically: all that happens is you give her information, weaken your position, and she will feel LESS motivation to reach out.

Instead you have to train them to be more active, right from the very start. As a man you have to do all the firsts..... first chat, first "reaching out", first kiss, first fuck. But after 1-2 of these, you encourage her to be more active... "Sure girl... ok, drop me a line in a few days when you're free". That sort of thing. And you also do this by being more passive yourself.

Don't let girls corner you into being the "person that does all the work in the relationship". Even with their "abuse" lies. I tell you this: they have ALL been abused to hell and back if you believe their stories. But their "abuse" is nothing compared to what most men have to go through.

This girl won't change, but you can find better in future.

lied once, will lie again.

would fuck her a few more times or try to keep her as a plate.

if you take her back she knows that she can get away with lying.

just my two cents, maybe there a better ways to handle this situation.
