I finally cut him off

I was with a guy for almost a year (my first serious relationship, the guy that took my virginity). I tried my hardest to be the best girlfriend I could be. I was there for him 24/7 through everything (and there was a LOT we went through together), and I was blinded by my love for him. He cheated on me, and after I found out, I discovered he had been cheating on me throughout the relationship. I was devastated. Fast forward about 3 weeks and I obviously still have feelings for him... he moves in for circumstantial reasons regarding his family life. I still live with my dad and sister at home, and they knew we broke up so it was a little awkward at first but not as much as you might think. He stayed for about 3-4 months and gets on his feet enough to move out and rent a place on his own. He’s epileptic and has never had a seizure in the time that I have known him. Can you guess? Yep, has a seizure the week after he moved out (also just so happened to be my birthday). So he called me right when he felt it coming on because he knew I’d be there for him (which I was) and I was the only person there. I took care of him the whole day and we moved on. As we were trying to maintain a friendship, he would tell me things (not necessarily tell me just to tell me, but rather mention something about what was happening) that he knows would make me feel very uncomfortable and sad; things like he was going to meet someone or go on a date or fuck someone. So I dealt with it in hopes to remain friends. Well, when I finally did the same, something along the lines of

Him: “I fucked someone last night”

Me: “Me too”

He FREAKED out. Saying things like “don’t ever talk to me again, lose my number, I never want to see you again, I’m dropping out of school so I don’t see you anymore (we go to the same college)” etc. long story short it wasn’t the best friendship. We talked about it and I finally decided that if I ever do wanna be friends with him, I have to get over him first. I told him I’d call him when I’m ready but until then not to contact me. I am sad, and I do miss him, but I know that I needed to stop talking to him for now. Has anyone else had similar experiences? If you have PLEASE let me know what happened, how you dealt with it, if you guys became friends, etc
