Fascinating. Hard to imagine what she was thinking. My dad, btw, was charismatic, extroverted, fun, good looking, smart, hard-working. Nothing about his life with my mother would suggest that he would have been a bad husband to his first wife in any really significant way.
Personally I believe that in many cases that the person who cheats has a decent spouse at home. One of the reasons they feel confident enough to go a-wandering is that they know that the home fires are well tended.
If the 1/2 dozen or so cheating spouses I personally know, I can only think of 2 where they were married to a jerk.
I have a hard time believing that it's a "thing" but I understand that there's a whole sub-culture of "predatory" people looking for happily married spouses to poach. An acquaintance of mine once said that if he were ever going to cheat on his wife that he would pick a married woman because she would have too much to lose to get attached. On the other hand I've heard of women targeting men who seem to be stable, good providers.
Ah life's mysteries.
