Fidelity in marriage is as important as can. Be imagined, and that explains why so many marriages have failed owing to unfaithfulness of either party in the union. There are instance where a wife could go outside the marriage to get pregnant for another man, usually without the knowledge of the husband. Such men would naturally see such a child as theirs! unless there is information to the contrary. Therefore, should he still care for a child who his wife confessed is not his?

What difference would it make if he stops providing..

Yes
His already taken the child as his , you can't just turn if off
He should do the right thing he is the only father the child knows and trust me God will bless him

As for the wife hmm na between her n God ..

See question.

She should simply take the child to his father.

dear wife, that will be very hard biko

If I v d resources I can take care of any kid....muchless my step child
