Phew! Ok, so I got our shared cell phone bill a few days ago...noticed a familiar number that I don't remember either of us calling before, showing up nearly every day since about a week after she left, and the calls escalating in frequency at odd times of the day. Most notably was the pattern of calls to this number right before and after her work. Then it dawned on me...I had this number in my own phone book! This guy is a piece of work...a guy who I have known for years, and who has been after my W since we got together. Now, the meanness, the nonchalance with which she has walked out and the projection of her guilt onto me as the bad guy makes all the sense in the world. I have not made her aware that I know anything yet, and have decided to let her file. She recently sent me an email and actually asked if I would pay half the filing fee! Whuh? God knows how long she has been involved with him, but I have a good idea when it began. So now, should I tell her I know about the A, or just keep it to myself? I have so many mixed feelings about it, and I am not sure I even want her back now. If she would do this less than a year into our M, then why wouldn't she do it again?
