This is a long post, I'm so sorry, there is a TL;DR at the bottom. I really hope someone will help me.
So I was a virgin when my boyfriend and I got together and started having sex. It was really awful and painful. (I now know he was much larger than normal, and I have minor vaginismus, but at the time I thought the problem was all with me)
But he always loved it and said how it made him feel so close to him and like how he felt like he loved me more when we had sex. I tried to tell him that I wasn't really enjoying it, but he looked so sad and upset, I felt bad being the one to ruin it, so I said it was probably just cause we were starting out and I pretended I liked some of it.
But like, as time went on it got worse and worse, and I hated it so much, until I started to get really upset and afraid every time he touched me sexually without warning, or looked at me a certain way, or twisted my words so they were sexual. But again I thought the problem was with me, and he always got really down whenever I seemed uncomfortable, so I usually just pretended to like it. He still seemed worried sometimes, but I always insisted it was fine and we should keep going. It was almost like the more unhappy I got, the better an actor I became.
And like, eventually the sex got violent, and he started to identify with the bdsm community, and he wanted to do all this stuff with ropes and paddles that sounded horrendous. But I was stupid and loved him and again I agreed to it, and I did all this awful stuff, and I found the only way I could get through it was if I dissasociated, and started going to all these places in my head I used to do when I self harmed and I still cry when I think about it for more than a few seconds.
And it was so messed up, I should never have done it because it's got inside my brain now and and I can't get it out. But I thought we'd be together forever and I wanted to be the perfect girlfriend. I thought if I couldn't get over this stuff with him I'd never get through it with anyone.
After two years ago we broke up. And I sort of realised that all of it had been for nothing. And for a long time, I was in a very, very dark place I won't go into the details of. But now, to an extent I'm over him, like I've been dating again for a while, and I have a wonderful new boyfriend who I feel comfortable with. But I just can't scrape him out my mind. It's driving me insane. Sometimes I just still feel his hands on me in the shower, or I can't sleep cause I feel filthy and violated. Or like I get really anxious right before penetration because I'm having flashbacks. One time my friend jokingly whiped another friend with a belt and out of nowhere I just had a panic attack, but I couldn't explain why to them.
And I don't know what to do, because it was so long ago I don't even hang out with any of the same friends I did back then so I don't know how to broach the subject with anyone. And I'm scared to tell my new boyfriend because I feel like saying 'I'm not over my ex' could come out so wrong. But I really have no feelings for him anymore. It's just it's also my new boyfriend's first relationship so I feel bad dumping all this baggage on him. Because I get that it's way too much for anyone to deal with.
And recently my ex has been reaching out like he wants to be friends again. And part of me feels like that could give me closure, like someone I could actually talk to, but also it still freaks me out to talk to him. I feel like him being in my life could just cause me to regress. And I sort of resent him, because even though I never said "no" to anything we did, I feel like maybe he should have seen how uncomfortable I was (because I definitely brought it up a few times) and stopped it way before it got to the stage it did. But I don't know how fair that is. Mostly I just hate myself for ever agreeing to it. And anyway, I don't really want to talk to my ex much when I'm in a new relationship.
I'm just so confused. It's been years. I don't know how to get over this.
TL;DR: I consented to horrendous, painful sex and kink I hated for many years, I can't stop having flashbacks even in a happy relationship.
