IDK, Mozza. I never know what to do with that kind of info. Way back in a day I wrote about how my H became estranged from his parents after they D'd (he was 25). Like cheating, family estrangement also runs in families and some say it has a genetic basis. Actually when H and I went to a few MC sessions soon after BD, the C said something to the effect that I might want to re-consider having kids with the man given the potential to pass that trait on! What was I going to do - D my H on the off chance that our kid may one day abandon us?
What if cheating does have a genetic basis? Maybe that's why your WW cheated. Maybe its not. Sometimes I think its easy to read things like the NYT article and think "ah...so that's why the WAS left"...and remove our role in the mess. (Not saying that about you...you've clearly put in a lot of work the last many months...but I think we need to be careful not to see an out).
I think the truth is probably in the medium. There probably is a genetic basis for cheating....and that dictates how we will behave if/when the circumstances arise (unhappy with current R + presented with potential suitor). Personally I think no-one is immune.
