Baby daddy

So the father of my baby up and kicked me out and told me to have an abortion at 2 wks when I told him he also said he would pay for the abortion. I made my decision that day to leave him and now 20 wks later he wants to be apart of the baby's life but now at this point I have moved forward with mine and my baby's life and no longer want him around he has anger issues and drinks and I don't know what to do I need advice from people who have been that I have been so happy with out him around and now I'm more stressed then ever now that he is trying to come back idk what to do.
