Is it a bad idea to become friends with an ex?

I dated my ex for 6 months and known him for almost 3 years we broke up because he mistreated me, constantly disrespected me, cheated on me with his babymother and told her about our relationship problems we have been broken up for 7 months and he always reaches out to me every few weeks. he asks if we could be friends and i tell him no and then I don’t hear from him for a few weeks. Lately he has been a little more consistent with asking me yesterday he asked if we could meet up and talk. I agreed and when we had our conversation he told me he loves me he doesn’t want me completely out of his life He only left our relationship because his baby mother was hurt that he moved on and she also got a restraining order against him when she found out he moved on and would only allow him to see there child if he got back into a relationship with her. He claims they are not together anymore and they are coparenting and now he’s asking if we could be friends should I just cut him out my life for good or give him a chance at being my friend
