My wife is pregnant with another man's child

Ok sorry to get personal but why has this happened in the first place? Has it happened with your ignorance or acceptance? The reason I am questioning you is that you would have been aware of this situation, if not-you should have been...and taken preventive measures then.. Try digging deep for a reason... If the reason is adultery, let her move on with the other man... Not because the child isn't yours but because the other man is responsible enough to bear the responsibility of his child and trust me your wife too is supporting him. They are in this together. I understand the feeling of depression and betrayal but at this point any force or coercion will harm you... Let her move on...you gracefully move out of this relationship...
