since my wife left 6 months ago, some of my kids asked about her affair 15 years ago, and I let them know generally what happened. They do not hate her per se, but they do give me some credit for not holding it over her head (ever)and staying with her and making things work. after hearing for most of their life what a terrible dad I was, they are old enough (30-19) to make up their own mind on things now, and they certainly are beginning to see things are different than what they heard for so long. I do not tell them with any amount of pleasure though.
