I know its horribly unpopular to bring this up these PC days, but some people might actually want to have a child that is theirs genetically. The man has that right. If the child is hurt, that is the woman's responsibility for her deception and unfaithfulness. I guess all men should be forced to pay the price for women's dishonesty?
All I'm saying is why should the child be made to pay for what his/her parents do wrong?
I think both parties are at fault here, don't misunderstand me. The mother should be made to pay him back the money she defrauded him and apologize to him as well as to her daughter for lieing to them and deceiving them.
But at the same time I don't feel he should be punishing the little girl for something she had nothing to do with.
