Am I wrong for wanting to take his child?

So I married this man on Dec 21.. 2 days later he left and didn’t come home for a week.. he was out at a girls house, sleeping with her. I tried so hard to fix things between us and just let it go but he was constantly picking fights so he could leave and go to her house. We started arguing one night and I just tried to walk away and he kept pushing on me and he poured a 2 liter drink all over me and I threw the bottle at him and he picked me up and slammed me on the ground while I was pregnant. After that, I left. He could have killed my child and didn’t even care. He’s now dating the girl but constantly texting me how sorry he is and he loves me and he wants his family and he wants to be apart of his child’s life. But I feel like he shouldn’t be around the child. He could have killed my baby. Also, after leaving I found out from his cousin he did the same thing to his previous baby mama. He drug her off the bed and down the hall by her ankles 9 months pregnant. Would I be wrong for not wanting him to have anything to do with his child? not be there for appointments, gender reveal, or baby shower?
