going back to my abusive relationship

i recently broke up with my boyfriend of 6 months cuz i found out he cheated. he claimed it's a joke but idk if it was. it didn't seem like one at the time but i don't know if i over reacted. anyway he was pretty controlling and hit me once. he was going to therapy to help cope with his anger 3 times a week cuz he didn't wanna lose me. then the cheating thing happened. i do love him and i miss everything we used to do together. i miss us talking 24/7 and hanging out all the time. but idk if i'm feeling like that cuz i'm lonely or what. all my friends don't like this guy. and idk if i should just move on. would it be a good idea to get back in this relationship for the second time?
