Would you agree that an open marriage can bring happiness to a troubled couple?

I read about such cases, and is usually a housewife with 2 man. If the is the other way round, the woman should have sued for divorce and take everything the man own. It is obviously that the Husband is not happy about it but in his greatest sacrifice to the family. He accepted the fact and learn to live with it. keep adult stuff out of children life. If they want to swing then stick by the rules. -.-
