The other woman contacted me a few times. I do know her and I do work with her. She tried to get under my skin and at first I let her but the fact that I did not respond made me feel good about myself. Because the fact of the matter is is that it is not about the other man( in your case) it is about you and your wife and that is who you need to deal with. The other man is just going to make you feel like crap. I know the other woman tries to justify what she is doing in so many ways in my case. I would say out her to her friends and family. Think of it like an intervention. I would leave the other man out of it because it wont do any good.
