This is certainly a provocative topic, and from what I've read, one of the least tolerated by Americans, despite the fact that so many of them do engage in extra-relationship liaisons of one form or another. Although most people will agree that lying to your partner or changing the relationship agreement unilaterally is not desirable, hearing someone talk about the practical sides of this dynamic rather than just the moral ones is refreshing. I'm glad you found your way to a relationship where you no longer have to be dishonest in any way. Those are the best!
