To be honest, you've busted your divorce so continuing on sites like any of these marriage-savers might actually be detrimental to the continued rebuilding of your M. In the grand scheme of things in this wicked world we live in today, you came away pretty lucky. Count your blessings on that won. Be the leader your family, and wife, needs. Make sure to water the grass in your life regularly or it'll start to look greener elsewhere. Set boundaries for relationship with your wife and both of you adhere to them.
If you forgive her for this then you have to really forgive her. It can't be brought up again later, it can't be held over her in any way. If she is a good person then she's punishing herself far more than you ever would anyway.
Let me ask, are you a person of faith? If so then take any residual anger, resentment, etc. from all this and surrender it to the big guy. Give the burden to God and he'll scrub it all from your heart. I was never much of a religious guy myself but I did this after my wife's affair. I forgave her and gave the burden of the rage over it to God and fortunately he took it. Today we're more in love than we've ever been. There is no resentment in our household. There are no secrets in our household. I am the leader of my family. Emotional leader, financial leader, and spiritual leader. I will love, honor, and cherish my wife until my last breath.
I think you're heading a good direction in your life journey. Keep it up and count your blessings.
