Please help..

I am a ftm and 33w pregnant. My baby's father left when I was 26w pregnant. He is a convicted felon (for drugs) and is on parole for at least 5 years. He has anger issues and thretens me. He makes me feel so worthless and like I won't be able to do this alone. I've tried to get him help and work things out for the baby but he went off the deep end when he left. He's threatening to get custody when the baby is born. I've done everything on my own for the baby and paid for everything. He lost his job and doesn't have a place to live. I had to contact the police the other day because of threats and am afraid of retaliation for it. I don't want my baby to be around him with his problems with drugs and anger issues..
