I am recently divorced and my ex was "dad" to my child since he was a toddler. Since the divorce, he will not pay any money toward him and my son, for his own reasons, does not want anything to do with him. Bio dad is in the picture, after I located him. He's thrilled that I found him and wants to be dad in every way possible. How do I tell my son that the dad he's known and won't have anything to do with now is stepdad and let him meet his bio dad?
