Then walk away get a lawyer draw up papers with him giving up parental rights. If he doesn't agree then get him on child support. He can't have it both ways. Get a paternity test once the baby is born to prove in court if you have to that it is his make your life with out him it obvious he has some issues and your baby doesn't deserve that. So do good by your child. Grow up a little and except you decided to be a parent. If not it isn't too late to put the baby up for adoption if you know for certain you can not give that child a stable healthy life. Good luck
