I caught my wife cheating but I haven't told her I know yet. I just don't know how to handle it. I found our bedsheets a mess one day a few months ago and wondered what was going on. There were other signals I started to notice. I started noticing evenings when her mood was pretty carefree and she looked like that cat who swallowed the canary. I started taking some time off here and there to watch her. I finally caught her a months or so ago when I followed her to a low end hotel and saw her go to a room where she stayed for a couple of hours. I waited for awhile after she left and saw the male half of a couple we frequently socialize with leave the room. My heart sank.

Since then I've managed to get looks at my wife's emails and texts to and from him. Their conversations lead me to believe that their relationship is purely physical. My wife feels guilty and wants to stop but apparently he has her wrapped around his finger. He starts talking about her body and what he's going to do to it and before long she's agreeing to meet him. I've managed to be there the last four times they've met. Twice he came to our house and the other two times they met at a hotel. I stood outside their hotel room door the last time and could hear them inside obviously having sex. I wanted to kick the door in to confront them but decided not to. I'm miserable.
