To which men are you referring? My father doesn't cheat. Nor does my boyfriend or my best friend's husband.
If your man cheats, that does not automatically mean that all other men in the world cheat.
Some men cheat. Some women cheat. It's nothing to do with the "good women" (or men) they have at home.
It's called "POOR CHARACTER."
P.S. Did Leona send you?
