Should I take him back or not?

Ok so my bf and I had a baby 4 months ago, he cheated on me when she was almost 3 months old I stayed with him, then he got feelings for her and so o broke up with him, he came back twice saying he wanted me but hen got mixed emotions for her again. We broke up because I was.over it, he had sex with her 5 other times, the entire time him and I have been contemplating about being together, he was constantly hanging out with his friends he used to sell weed and started again! He got suspended.from work, then I found out that he had sex with another girl he used to date and she sent.me texts of.him saying please give me.another chance I want to be with you. Now he's saying he realizes.and he loves me and people can change? He's screamed and yelled at me since we've broken up to.and called.me every name in the book. About a month and a half after.my baby was born he proposed, I accepted, and we got in a rout and he called me ugly and I called the engagement off. When I started crying he was extremely apologetic. Weve been together for 3 years technically 6. He messed up before and chased me for 2 years, did anything he could to see me. I want my family together, its affecting my little girl. I sill love him should I take him back?
