I'd think that most hot women annoy their man to some extent and another flavor is desired. From my viewpoint, men (and women) who cheat do so without much regard to what they're getting at home and from whom. The grass may not be greener but it's grass that must be sniffed and peed on.
There is truth to that. Case in point - about 15 years ago, a chick invited me to a pool party. I was single, so obviously I went. There was a dude there who was a pretty cool guy - personable, intelligent, liked good beer, funny, etc. But he wasn't a good looking guy. He was portly, hairy, etc., and he wasn't rich. Basically a middle class guy. His wife was a 10 and might have had the best body I've ever seen in my life. She was running around in a skimpy bikini, and everything on her was perfect - a true marvel of nature.
Obviously, I wondered how the hell this guy landed this chick, and frankly I was envious. How good of a bullshitter can one guy be?? Brad Friggin' Pitt has not done better. About a month later, I figured it all out. I met up with them at the Waterloo Icehouse on 360, and that girl was the most smug, rudest, and most obnoxious girl I've ever met. She picked stupid arguments with everybody at the table (including me), was rude to our server, and insulted and demeaned her husband every chance she got. He literally had to tell her she was embarrassing herself and to "shut the hell up." I'm sure plenty of guys would "go there," but only this poor sap who knew he'd never find a woman who's even in her league in terms if looks would ever "stay there."
Will that dude cheat? Maybe, and it definitely won't be with a hotter woman. He'll never find that, and he'd never have a chance even if he did.
However, Trump's situation is different. First,I just don't believe Melania even on her worst day is that colossal of a *****. I just can't imagine it. Second, Trump can get women with his money. He doesn't have to settle on a filthy porn actress.
