A colleague of mine several years ago had the same thing. She was married with 5 grown children, went to her HS reunion, started an online EA with an old BF, turned into PA and left her husband.
Last I heard, she and H were back together.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
