Should i reconcile with my husband?

My husband and I were married for 7 years and we have 3 small children. He most definitely wasn't a great husband at all. He cheated alot, was abusive mentally and physically ( the physical aspect was off and on). We just recently got divorced in April. He says that it took me leaving for him to wake up. I see some differences in him. His attutide about our kids has changed quite a bit. He was never an attentive father til recently. My son is 6 years old so he was present for most of the termole between me and my ex. He started acting out towards me. Yelling at me, calling me names, etc. My ex actually sits him down and tells him that he can't talk or treat girls that way. especially not me. He sends me messages everyday and calls me everyday to try and talk and has asked me to go out with him so that he can prove he's different. I do love him still. But i don't know if i should try to reconcile. When we first go together my family and friends try to tell him that he was bad news but of course i didn't listen. they dont have very much interaction with him at all but they all feel the same way as they did before. I am scared to go against them this time because they were right the first time. Should i try to see if he's changed and work things out if possible? Or should i stay with my family.
