Questions: Break Up & Divorce

Assume you had thought your wife was straight. Would you react any differently than if it was with a man? Would you be relieved? Would you feel more inclined to forgive her, and would you possibly find it hot? Or would you be just as angry, if not more so because she hid her attraction to women from you? This kind of thing happened in a movie I watched recently. The wife came home late one night, her husband didn't beat around the bush and was waiting for her, and he asked her who she was with. She let it be known she was with somebody else, without revealing that it was a girl, and he was rightly pissed off. They were planning on getting a divorce, she was kicked out of the house, etc.. And then a few days later they met up because she wanted to explain everything. She told him it was with a girl, and his anger just evaporated. She was instantaneously forgiven, and I believe it actually turned him on, because they shared a pretty passionate kiss after that. I was completely baffled. I mean, I know a lot men are really into the girl on girl thing, but it's shocking to me that such a blatant display of disloyalty and untrustworthiness could be excused. Regardless of who it was with, regardless of why she did it, she still cheated on you. Really curious about this.
