This is a serious issue, all of them are at fault. Though the husband made a lot of mistakes. He should have pled after misbehaving. I think the best way now which i know will be difficult is for the family to hold a meeting and resolve issues inorder to make peace to reign. They should think of the fact that the guy never married another lady even though he didn't married her legally. Something, I do see certificate has paper because it can never hold two people together though it serves as a symbol of the love.
