A dear friend of mine is going through a divorce after only being married one year, and has a son who is 2 1/2. He has just discovered after 2 paternity tests that he is not the biological father of this child. The mother of the child knows who the biological father is and refuses to tell him. Is he still responsible for being the father to this child emotionally as well as financially? Is there anything he can do? I appreciate any kind of advice or knowledge that can be shared. Thanks -
