In the past few months, I found out that my wife is having an affair.  She doesn't know that I know, yet.  The guy she is doing it with is an ex of hers and she always commented on his size and how he used to fuck the shit out of her all the time.  We have sex all the time.  I don't know exactly why she is doing it, but part of me wants her to continue.  Our sex life has been on fire the past few months, since I found out that is.  She's always been very sexually demanding and has a super high sex drive.  I know she doesn't love him because she detests his personality.

I drove by his place the other night when she was supposed to be at the gym and her truck was parked around the corner from his house.  I was super angry and almost went to the house but then I thought if I confront her, she'll stop, or maybe we'd get in a big fight and break up.  We've been together for almost 22 years now.

I heard rumours about other affairs, and now it seems they might be true.  

I plan on confronting her but not sure how to do it, quite yet.
