Every novel I've ever read in which a "nice guy" steps out for a minute on his wife monkey-style that's how he behaves towards the OW. The Madonna /whore male shame thing again (yawn).
Well MO, I suppose there is lots of shame for most NG's I had tons of it (shame) dumped on me. You don't have to be Catholic, BTW.
Denial and shame, you see both on the "Cheaters" programs on TV. Very few guys say, "yes I f'ed he and it was good" so it (denial and shame) seems to be the default setting for most people that consider then self "non-players" but greatly troubled with their home life.
His behavior during this incident was dysfunctional monkey both in regards to MissIC and the OW. So guys, watch "Cheaters" to learn what not to do.
The show reminds me of shop-lifters. People want something but don't want to obtain it honestly and openly.
