I can't imagine being in a situation like this. Please keep in mind that the ball is in her court and at some point, I would think, she will realize that she has to make a decision to honor her vows also or move on. I hope that it works out for you. This is not the first and won't be the last marriage to deal with infidelity. And sometimes it actually works out in the end and people move past it. I hope that will be the case for you.
