I think that OWs tend to be more attention seeking and fixated on the wife than the typical OM. I think most OMs would not seek out the husband, whereas many OWs (including my MLCer's) invite contact with the wife.
From my experience, I would agree with this.
I knew the OW many years prior to this due to work, and while she has kept away from me at all costs since BD, at the same time she has stalked me and talked of hacking into my email account, and has subjected me to a barrage of hang up calls.
the affair is an aggressive act on the part of the OW. I think she works out many of her anger and dad issues and jealousy in this dynamic and so for a betrayed wife the situation is actually one of meeting an aggressor.
Clearly a very messed up woman, it creepily appeared for a long time that I was as essential for her fantasy, as I was to my MLCer's MLC two life fantasy.
Finally having a settlement after 6 years has allowed me to now step well away and leave the two of them to it.
Apparently she now has 'cancer'. Not sure if it's the workings of karma or the workings of fiction. Time will tell I guess.
