Not sure how to help, but as a child with separated parents I can say that getting together or staying together just for the sake of a child is not the way to go. My parents tried many times to be together again for my brother's and I's sake and it only resulted in more hurt, confusion, and anxiety in the end. I prefer my mom with her boyfriend and my Dad with a woman who makes him truly happy.. not with each other.

It would be good to work something out so your child can see their father (if he is up for that) and you can be supported financially.. but I don't think it's a good idea to try and start up the relationship again, especially since you can't be together because of these legal matters.
