Paying child support and child ...?

I am so sorry that you have to go through this baby daddy drama. Don't worry about explaining to this jerk what is going to happen-the good, old courts are going to tell him, after paternity is establish. He sounds like the type to go around saying it is not his kid because you won't give him any play. But, please be caution that if he is establish as the 'father', he is going to have certain rights to the child (i.e. visitation)---unless you can demonstrate that he is a danger to the child. Good luck!
