lol ... HAving read various people's comments on affairs in responses to other questions, I'm beginning to think I have a very peculiar view of things.
If my wife had an affair, I might be hurt (it hasn't happened so I don't know) but one thing I would want to know is why it happened - as in what was I doing wrong that led her to have an affair. Then I'd set about trying to fix what was wrong.
It's strange how ideas and attitudes change - at one time, and in certain classes, an affair was considered acceptable provided it was with a married woman who had already had children. These days, couples happily live together with no thought of marriage, we refer to our partner rather than husband/wife/boyfriend/girlfriend, live in a world where porn is readily available, erotic images are used to sell things, and cheerily discuss all manner of things which would once have been considered private, and then throw a tantrum or go into teenage angst mode when someone has an affair instead of trying to sort out the problems which led them to having the affair in the first place.
Oh well, 'tis the times and the manners
