Hi. Have you heard of open relationships? I wish my boyfriend didn't want one. Does he know that it is an relationship which is non-monogamous? It is consensual as well. I don't think he does. It needs to be a mutual decision like the game. The game also involves a romantic breakup. How long has the idea of an open relationship been around?
The concept of an open relationship has been recognized since the 1970s.
