Recently broke up w my boyfriend cause he’s done stuff to me while I was passed out twice, he’s cheated on me twice and has lied to me multiple times throughout the course of our almost 3 year relationship

I broke up w him because I found out he was talking to girls he used to like and he unblocked a bunch of girls on Instagram that sent him dirty pics n than blocked them back so I wouldn’t find out but I didn’t

I broke up w him and I feel an urge to go back to him like my heart hurts and I don’t want to feel this way I really don’t I just want to be over him and move on but I’m feeling this weird pain in my heart

Any ideas on how to get over him fast,

I’m trying really hard to stay away, I haven’t cried or anything I don’t feel any emotion toward him beside that pain I feel in my heart which sucks
