Jason, You obviously don't have any idea what this man is going through. You should be helping him not telling him to leave you alone. I happen to know what this poor man is going through. Two years ago I found out after almost 40 years that the man that raised me was not my father. I did find my b father and it was a blessing. Him and my mom are together once again and it is great. You need to understand that this man is in need of finding his son and by all rights should know where he is. Your mother was wrong and the only reason he used yours and your sisters names was because you two were there at the time he is only using information that is all. Tell him where to find your mother and leave it at that. Don't discourage him help him. Stop being selfish and grow up.
