I am pretty much in the same boat. My wife has been having an affair for about five months. She moved out two months ago. The guy is a complete loser with a pregnant girlfriend. He lived 100 miles away had no car no job and no place of his own. Now my wife has bought him a car that he can't legally drive and I think he's probably staying with her.
I know how over it is but that doesn't change how I feel about it. I know how much of a piece of **** she is for doing this to me and our children. I can't stop caring about her. I can't get a full nights sleep. I miss her here. I just hope that in a few more months it won't feel this raw. Reading a story like yours now I am concerned what I'm going to have to do to move on.
