feeling guilty 😭

Okay so me and my ex boyfriend broke up almost to months ago after dating for almost 6 months, we fell inlove so much. Nobody could separate us everyone wanted to be us. Before I got with him I was like such a goody goody nice to everyone never did anything bad wasn't sexual or anything. So when I met him he was 17 and I was 14 one day we were talking and I said I wanna sleep with u and I don't mean sex I just mean fall asleep in your arms and he said back "oh there's always time to fuck" so right then my mind set changed, I became more sexual did stuff for him I wouldnt have ever done and wouldn't even care if people saw. Well, I was pretty sure his mom was fine with it bc her and my ex bfs dad was really sexual so I got used to talking dirty all the time and making out in school. So when my bf broke up with me it broke my heart bc he meant the world to me and I had totally changed for him...I found out the reason he broke up was I was being too sexual and now I can't forgive myself bc I feel so guilty but at the same time idk if he really broke up with me for that reason bc after all he was the one wanting to fuck all the time....idk what to do he blocked me and hangs up when I try to call....I saw him today and just started crying. I want him back and Idk what to do to get over him. I miss being in his arms so much😭😭😭😭😭
