I really need help, I know this is long but please.

I found out last night that my girlfriend of over a year, step mom to my daughter, is a chronic liar. Seems like she just can’t stop.

Background on her:

Abusive household. Dad hit mom, exploited her sexually for money, etc.

She has been exploited sexually also, but by her own hand - a choice during hard times.

Has trust issues with men, without a doubt. Been stalked before, etc.

HOWEVER, she’s into abusive sex. Role play rape, rough stuff, etc. She’s into the idea of pretend stalking leading to sex. Because she gets to control it all this time around, she gets to take control of things that had control of her. It helps the trauma....

Examples:

-has a cute pet name for me, swore a million times she never said it to anyone. Found out she did, with proof

-Said she had never said anything gooshy or sweet to a man before. She has, with proof.

- Said shed never sent nude pictures, then admitted it 1 year later, accidentally, during a talk.

- Said she didn’t have sex with this guy she knew, then admitted it later on accident during a conversation.

- Said she never had a conversation with this other guy, turns out they had rap battles and talked about cars, again, admitted later during a story she told on accident.

- Said she doesn’t watch me on GPS (find my friends) then I caught her and she finally admitted it.

- SAid she doesn’t snoop through my phone, again, caught her and she lied about how much (only a few times) then I found out how to tell and it had been a LOT.

- She was reached out to by an older man she had a relationship with but broke her heart.. she hid it from me for 8 months before be backing her into a corner and her admitting it.

All of them are things that I’d NEVER be mad about... but become mad because I only ever get the truth when I find proof....

I sat her down and we talked from literally 12AM until 7AM, then the next day about 4 hours, then yesterday abou 2 or 3 hours. She swore and swore that she’d stop, I explained building trust needs to happen right now and she was on board.

Then last night I asked her a question, I already knew the answer, I just wanted to make sure she would tell me the truth... because I obviously have a lot of reasons to believe she wont.

I asked her if she watched me go to the gym on GPS.. because she just so happened to come to the same gym while we were in an argument and she pretend to the death it was a coincidence..

I found away to find out the last time she looked on GPS.

I asked her if she looked, she said no. 5 times over the course of 2 hours...

She lied.

But not only that!

She then flipped it so it was MY FAULT. She lied and said she knew she was lying so that she could get one over on me by proving I was “backing her into a corner” then she said she knows I’ve been watching what she does on her phone, like with spywear or some shit, so she said she lied to try to catch me!!! I ABOUT DIED. She got angry, pointed her finger at me and tried to convince me she lied so she could catch me! That it was all a big ploy to prove that I’m an asshole. Fucking joke...

So I sat her down, was very sweet, and told her basically that I need her to tell me the truth right now, and if you dont, pack your shit and get out of my house.

I asked her if she lied about all the crazy shit she accused me of SIMPLY to try to cover her ass that she lied about the first thing.

I was so sweet, so gentle, so loving, and so stern that I would never look at her again if she tried to uphold flipping the lie on me.

She admitted to it. Finally, and wholly. Said she panicked and didn’t know what to do.

I explained to her that she literally has a problem with lying, she’s a chronic liar, an addict of sorts... She understood and even kind of admitted to this fact.

What the FUCK am I supposed to do???

I’m madly in love with her, and she with me.. I know she’d never cheat or do anything serious like that... but good lord I can’t believe a word she says. What do I do? I want to rip my hair out, cry, and punch every wall in my house..

Please help me :(
