My wife is pregnant with another man's child

Definitely a divorce. No man is able to tolarate that his wife carried another man child. Unless u already know abt it before marriage and u are willing to accept that. Even if u said u dont mind or willing to accept another man's child, this incident will constantly be bring up should both of u get into a argument in future. That will eventually bring an end to your marriage, just sooner or later. Then why not end everything now, so u get minimum hurt. Since that man is willing to take responsibility, let your wife go.... let them take care of their own problem. Lastly, pls open your heart and let it go. Your wife doesnt deserve your love. Dont go into depression or hurt yourself.... Pick up yourself and moved on. You will find someone better in life......
