And I believe she mostly dated him at work. That's one of the problems with work; because people spend so much time at work, it's very easy for them to see other people there more than they see their own spouses.
That maybe true, but have you ever dated someone you worked with? That brings a whole new set of problems for a relationship. I have done it twice and should have learned my lesson the first time.
Her relationship with the OM, regardless of it being an E or P one, will soon come back down to reality. She will eventually start to see his faults and shortcomings as well. Just like so many WW's they are living in a fantasy world right now. They don't realize that every relationship has it's "honeymoon" stage and that the euphoric feeling eventually dies out. She may realize then that what she had with you wasn't so bad and try reconciling. Who knows, by then, you may not even want her back.
