Baby mama drama

So I started dating this new guy and he has 2 kids a 4 year old boy who is not his but he raised him and still takes care of him and a 3 year old little girl. I've been with him for maybe 2 months and he's been to jail 2 times for battery. First time he beat a neighbor because he called him a immigrant. The second time was him screaming at his kids mom and slamming the door open because her boyfriend was over at her house. Now I've been through jail stuff before with my sons dad but I don't think I wanna deal with this. He's super nice but I'm not sure what to do. Opinions ladies?
