i would forgive him if he was a wonderful hubby,if it was a one time meaningless lust driven fling, wouldnt let “society” know about it b/c its none of their business, their only purpose would be to have a topic to gossip about in their next gettogether. it does depend on the situation and the details do matter but if he’s a good man, this one little mistake shouldnt erase the 95% good times where he was a good,decent, loving, caring, respectful man.
we all have flaws and we’re constantly trying to improve ourselves, we aren’t perfect beings so it’s better to leave most of the judging to God…so I would rather know about what he had/has done.
