I agree with the others - maybe it's a view that's biased because of those of us on this side of the board who've still hung around maybe aren't a representative sample.
One difference for me as well is that my kids are both adults. They have their own separate relationship with their mother and presumably OM that I have nothing to do with and no direct knowledge of. I've not spoken to my ex in quite a while - more than a couple of years now and never met OM. I have seen them in passing from time to time and my ex makes great efforts to not encounter me - or so it seems.
I've not forgiven her, nor will I ever. OM deserves only my disgust. In the unlikely event that we are socially at the same event - a son's marriage or something, I will be polite out of respect for my son.
I don't find the lack of forgiveness limiting. She's a person who has only a peripheral impact on my existence. Time and distance were necessary to get there though.
