One of the most selfish things is the fact that the woman will not leave her husband and set him free to find a woman who REALLY loves him... She has nothing tieing her to her husband except a fear of being 'alone.'
Kids aren't the only ties that bind. Cake-eating is cake eating.
I'd say your STBXWH was a pretty effective liar - most of all to himself. Can you imagine the effort it takes to conduct an LTA? There is nothing passive there. He lied to you day in and day out, even if she handled the logistics.
Keep reading, keep posting. Your posts help many others too - lurkers and posters alike.
AFAIK most of the OW were single. Couldn't get a single guy so decided to go for a married guy. It's pretty easy to compete with real life when you're offering UnicornFartLand to a broken individual with little to no integrity.
I don't get the appeal of a married man but it has to have something to do with them being the lowest hanging fruit. Very easy to impress because they're being saved from the wicked wife who doesn't know what she has.
Too right I didn't know what I had - a lying, cheating, POS with zero regard for anything or anyone aside from instant gratification.
Soon enough the illusion fades and she becomes the wicked wife/GF. Once we are out of the picture there is a vacant OW position available. Someone to once again save him from the wicked wife.
Why is your sister friends with these people?
