Should I take him back or move on??!! I NEED HELP AND FAST!?

HIs name is malachi and we have been on and off for a while now and he does me wrong like calls me out of my name when he gets upset but i do the same thing!! and he hangs up on me i hang up on him! and other things like that! We had broken up 11dayz ago! and he has moved on to another girl but i'am still SUM-WHAT single! i mean i flirt and all and i have a boifriend but for some reason when he asked me if i was single i quickly answerd yes! he has hurt me alot of times and lied to me! i dont think i can handle us being together and breaking up again...its too hard! and i dont have feelings for him like i use too...but thats only because we dont talk and i avoid conversations with him! But when we had talked today i found my self so vulnerable to what i dont know! and i found myself trying not to make him mad and please him as if we were still together! and he has a girlfriend (rebound) and i told him to break up with her today or that wasnt going to be a us! but im not sure i want him
