I can’t stop thinking about it

Recently me and my ex partner broke up. We met recently and when he asked me how I was I told him I was suicidal and broke down crying. I told him instantly that obviously the break up hasn’t made me suicidal but the ocd that’s come with it has. I felt so bad that a few days ago I messaged him to say sorry for how much I’ve contacted him and for being such a mess. I asked him if he still wanted to be friends and he said we would but now I can’t stop thinking that maybe he’s just saying that because he knows I’ve been suicidal. I just want this all to stop, I don’t know how to stop thinking about all I did wrong and how much harder I’ve made this break up

I’m overanlazing alot of things. My first post on my profile covers everything but I’m so worried and like nervous reck of what my ex boyfriend could be doing. We are on no contact for almost 3 weeks now which is the longest we’ve ever gone. I’m getting so much into my head like if he already moved on, or if he’s talking with some girl already, or letting a girl hit on him. Or even going back to bad habits. It’s been driving me nuts for the past few days. I’m still mad at him for hurting me mentally but miss him too. I keep thinking there’s something wrong with me, wrong with the way I’m thinking, like I’m not normal for thinking these things. That he’d find me weird I wonder those things and that I check on his profile on instagram, just staring at it, blocking and un blocking him. I worry that maybe he doesn’t think of me anymore. And he just. Doesn’t care. I feel like an older version of him would say I’m being too much, that I’m overthinking to so many extents that even tho we are broken up, he’s single and so am I and I shouldn’t care this much about it. But I do. And I’m sure it’s because I’m still in love with him. Even if I’m mad and upset still.

My ex just told me I’m a narcissist and I haven’t stopped thinking about it for days now. He broke up with me for the 7th and final time now and I did have an avoidance compulsion but I don’t think it was all ocd because he would continuously make poor choices and I was feeling used by the end of the relationship. However I was still trying to convince myself it would get better and it’s just a rough patch we’ll get through eventually. I blamed my ocd because I didn’t want to give up on him and I feel like maybe I was just in denial that it wasn’t meant to be but I also wanted out for a while now. I felt guilty for feeling relieved when he broke up with me but it was a civil conversation and it seemed like we were ending on good terms. But now he’s telling everyone that I’m a narcissist and I abused him emotionally and I was controlling when I let this man do WHATEVER he wanted. I’m controlling because I said I wanted to do his hair because I’m literally a stylist. He said I’m just like my mother and I’m a sh*tty person. He sent me a long paragraph of why I’m worse than all of his exes and that I’m a bad mother days after we broke up. I know I should’ve handled the situation differently but I don’t think that should ruin me as a person. He also said he no longer believes what the men in my past did to me because I’m a narcissist so that means I’m a liar. Knowing one of my biggest fears is becoming the people who hurt me. Part of me feels like he knew this was an obsession of mine and used it against me. I really feel like the worst person alive right now. Like Hitler level evil. I normally don’t post much but this is ruining me right now and I don’t know who else to turn to. I’m out of options and I’m really just helpless right now.
