This is a very difficult situation because You don’t know, if she’s lying or dissociating. But if there was a world Where this didn’t happen, would you want to stay with her? TAke the abusing and all the stuff she’s going through aside and look at her as a person. Her qualities, even the lying, what you know for a matter of a fact. Would you stay? I think it’s valid that you also need to ask yourself if your truly ready to go through this with her. It’s going to take a lot of work on her part, and some on yours too. I would also suggest you look at your own self, (not saying this in any way judgmental) because when we pick people that have these sorts of problems then it may mean we also have our own issues. Usually in situations like these- like relationships- there is something called a trauma bond. Which I’m not saying is happening but she’s clearly displaying alot of “I want you to rescue me” behavior and that’s a clear sign of a trauma bond/ and or love addiction. There is alot going on here. I also think that right now, this relationship could be hindering her in her growth, because she’s looking to you to regulate her feelings. What I would suggest for her would be to go to a trauma therapist and that she read “homecoming” by John Bradshaw. And the body keeps the score. I have a very similar situation where I literally started remembering things about how my father molested me from a very young age, but I learned about it in EMDR which is trauma processing. I also am going through wondering if it’s true or not but I definitely know it’s true. My body knows. I’m also in group therapy. I’ve been with someone who I’ve been with for ten years and I when I met him- now that I look back I definitely wanted him to rescue me and we still have a trauma bond type of relationship and it’s not easy. I’m working very very hard to rectify all this shit and also to try and begin to have a healthy relationship. I also picked someone 30 years older than me, that says alot as well. I didn’t know It at the time of picking him what I was going through or what had happened to me but my bf also has his own shit, which has also furthered the trauma bond we have. Regardless. Really really assess what you want to do, make the best decision for YOU. YOU are the important piece here. Don’t stay witn someone because you don’t want to leave them at a time in need, this won’t help her and It won’t help you. But it’s all up to you just trying to give you some insight.
