If you're just talking about confronting your S with the A, there's nothing wrong with that. It depends how far you're going to take it. Some people have gone off and exposed to not just family, but to friends and employers as well. If you're doing it for the sole purpose of shaming your spouse and getting revenge, the chances of you saving the M isn't very high.
It's not "wishy washy" advice as specified above. You do, in fact, have to "improve yourself", or else why would they even want to go back to you if the problems still exist?
Bottom line is that it is up to you. Everyone has a right to proceed as they see fit. It doesn't mean that those who don't expose are "weaker" than the ones who do. It's a personal choice.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
