How do I leave?

I’ve been with my kids father going on 10 years had a break for 2 for the exact reason of what I’m going through now. He’s constantly accused me of cheating and it could litterly be anyone. Well he just admitted to writing females and even trying to meet up with one. He has physically and mentally abused me. I don’t know how to leave or where to start because he refuses to leave
