Well, my dad has never cheated as far as I was ever aware of... although he was involuntarily divorced (communism refugee) and then widowed... is now remarried, so he's had 3 wives so far.
My current husband doesn't seem to be unsatisfied, although we've only been together 6 years, not 40.
I have an elderly couple as neighbors, and they LOOOOOOOVVVVEEE each other. It's beautiful. He always lights up when he sees her and they always hold hands.
My stepbrother waited until he was 37 to get married, because he was looking for the "forever" woman. He barely dated... he said he didn't want to spend too much time on women he wouldn't be together with forever. He did find her, btw.
I can think of more examples that inspire hope than contribute to a bad reputation. Most of the men in my life (family, friends) are looking for a woman they can be loyal and committed to. The cheaters that I know are the exception, not the rule.
Does that help Rhap? I hope so... I hear the hurt in so many of your posts and I wish I could help...

You've raised three young men and I know that the dedication and importance that you've placed on your marriage will be an inspiring example for them.
