Just because a woman is “beautiful” by society’s standards doesn’t mean that she is a perfect wife and guarantees a perfect marriage. Men cheat on “beautiful” women just as quickly as they cheat on the less fortunate in the looks department - and vice versa.
If I married a woman, beautiful or not, I would not cheat on her (assuming she doesn’t cheat).
I have talked with people who have done business with Shania Twain and I have been told that she is one of the nicest, most down to earth persons you would ever know in the entertainment business.
Just because a man has a beautiful wife doesn’t mean he’ll respect his marriage vows and keep his zipper up where other women are concerned. Some men won’t even do it when they have a perfect wife. A guy (or gal) who screws around on their spouse shouldn’t be expecting perfection anyway.
