I'm sorry that this is happening and my heart goes out to you. What a jerk? He probably is afraid of the responsibility and the idea of having a family to take care of and he wants to back out now. He is very young, both of you are. But he chose to have a child with you and he has a responsibility to your child so i would focus on getting child support like the others have said. I would not think about getting him back i know you are hurt and betrayed and lonely and scared but you need to lean on your parents and try to focus on you and your child. He is immature and cruel to boot, to do this to you, why would you want him in your life? You deserve better please believe that, he is not worthy of you. Again my heart goes out to you as well as my prayers.
