In our case there has been no contact from the OW. She dropped WH as soon as I found out. On DDay I tricked her into calling his phone at 2 am and had a conversation with her where she told me in no uncertain terms that she was sorry and that she was not in love with him.
The thing is - I believe - that this is just her standard operating procedure. Picking up men like toys and then discarding them when it gets complicated. I think that she actually gets a charge off it. There was NO emotional component to their relationship. She never asked anything about his relationship with me and he never shared anything. It was all about getting drunk, getting high, and getting fucked.
My fantasies about contacting her are because I believe she never gives US a single thought. EVER. He is no longer useful to her so she has just added some more studs (married or not) to her stable.
Thank you for listening to my morning vent... :)
