Thanks everyone... I am holding off on any talks with her until I'm confident in my plan of action. The OM's wife has offered to get me additional info on the details of the affair so we can compare notes to give us the best view of what, when, etc. I'm not sure it's a great idea to be communicating with the OM's wife, but to this point she's been thinking that her and OM were working on their marriage. Only to be blindsided by this photo. I was at least suspicious of my WW. She was floored and just finally got full disclosure from him last night. Only reason I want to talk with her is because his full disclosure was significantly different from my WW's.
