It's called a marriage. It's just another fraud. Of course there are open marriages where both of them lie to and cheat on one another and know all about it. Maybe they share intimate details of their affairs with their spouses. A great role model for their children and maybe they let their kids know all about it too. Still. It's not what I would call a marriage. It's a business proposition isn't it? Is that what a marriage is to you? Could you live a happy life within that framework?
