I did contact the OM but he knew my FWW was married. Nothing good came from our contact, and when I was finished talking to him I felt nothing but rage. I then dedicated the next 3 months of my life to destroying his career and his relationships with the people around him. I was extremely successful at this, He then moved 3000 miles away.
I know to some this may seem like I got payback but I can honestly tell you it does not feel good. I wasted so much time and energy and I feel like I sold a piece of my soul for vegence.
If you are going to contact the OM to try and find out more info then please be careful what you ask for. It is quite possible that you only have a small amount of the truth about what really happened during your W affair. IMO I would leave the OM out of it and concentrate on your WW, she was the one that was supposed to protect you and your marriage.
