Should I get back with my boyfriend???

I recently broke up with my boyfriend because we had been fighting a lot. I asked if we could take a break because I had a lot going on in my life and I felt really overwhelmed. Fighting with my boyfriend was definitely NOT helping so I just wanted to take a few days apart. But he said I would “cheat” and he didn’t want to take a break. So I really had no choice but to break up with him for good. I want to get back together with him now that I’ve spent some time getting my life together but I’m not sure if I should. Throughout the relationship he would pretend to break up with me just to see if I would get upset/cry, because he wanted to know if I actually cared. His two best friends hate me and are WAY too involved in the relationship for my liking and they always try to get him to break up with me and say rude shit to me. We got into a big fight at the beginning of our relationship because I heard that he was telling his friends about how small my boobs are. When I told him I was still upset about this, he said “well it’s true so why does it matter”

I’ve been considering getting back together with him because I really love him, and even through the rough patches it’s been my best relationship so I’m scared to let it go. What should I do?
