This is a little of the story. I have been gone for two years and only getting home mainly on the weekend. My wife moved out a week ago, and this was a red flag on the field. I asked her several times if she was having an EA or PA with some guy, and her standard answer was no,no,no,no,no. . . .
My problem is that I am struggling with not telling the OM wife about the affair. The OM is married and has two children.
OK, I went back and re-read your first post here, and I'm confused. IS your wife seeing some other guy, or ISN'T she?
You say above that you suspect it, she denied it, but then you want to expose it.
If you're NOT sure about this (don't have proof), then there's your answer about your adult kids -- don't expose them to something you're not even sure of!
