I very much appreciate all the responses. Usually it's me giving out the free advice. But this one has left me speechless (I know that's difficult to believe). Have had a sick feeling in my stomach all day long.
You guys deserve more info and I'll try to keep it short...
She told my Wifey all about her affair so it's confirmed. She's 42 years old and is doing a 30 year old guy with a wife and three kids. The only thing I can second guess is that she claims it's her first affair in 13 years of marriage.
canovsp said it the best earlier... I'm convinced he will snap if I told him. He might come after me thinking I purposely withheld the info because our wives are so close. Or who knows? He may assume something worse.
This is a Marine Vet who I've gone hunting with several times and he's also got a couple hand guns. The only good thing is that they do not have kids. And then we have that Marine who went Postal in PA today killing his ex-wife and some of her relatives.
Think I need to sleep on this again tonight and find some kind of a way out. Or a way through. Or a way around. Because this is a miserable spot I am in right now.
That changes everything and puts you in a no win situation. I think the most important thing for you is WHEN ( not if ) he finds out, make sure he NEVER finds out that you knew before he did.
