I think men in general have a wake-up moment when they realize no woman is going to love them the same way their mother did, that romantic love does not work the same way as familial love.
And the worst part is, if you find a woman whose love feels like your mother's love, RUN.
I can't speak for all men because I've only really known a few dozen of them well enough to judge. But I don't remember me or any of my friends having or needing one of those moments.
The forgiveness thing is legit though. Our kids remember ALL the times we fucked up. Frustrated remarks that would roll off your spouses back are not forgotten by kids - because it hurts them more.
