This couple should file for divorce but no one really knows why they have not. He cheats. She cheats, although a little more discreetly because of who she is cheating with. They play this public game of happy marriage and family and try and sell it like they are running for political office or something. They are just a celebrity couple. B list for sure with almost A list name recognition. They don't share the same bedroom and rarely share the same house. They alternate custody of the kid(s). She started seeing a very powerful studio head who appreciates the way she performs certain activities in the bedroom. The husband cheats every chance he gets and loves being gone out of town because they both are trying so hard to not get caught and to have the world believe they are still together. They are not really trying to sell something that needs them to be together. It could be for the kid(s). Maybe. It is not like they have a book about fidelity or relationship advice about to hit the shelves. They could be holding out for a reality show. They both have experience with that.
