MJTT,

This is a long process and you're just in the very, very beginning. You've talked a lot about your W but you haven't said much about yourself. What are YOUR issues? We all have them. I would encourage you to give her some space and time and then spend this time working on YOU. What can you 180? What can you do to GAL? You need to show your W that you are a rock star with or without her.
You need to determine what made you M vulnerable to an A. Can you see what was going on in your M that allowed the A to become an option? Nothing you did or didn't do was responsible for the A. In the end, it was a series of very poor CHOICES that she made and she alone is accountable for that. But somehow, your M became vulnerable to an A. Figure out what that was and work on changing those things.
