Here is what I think, having dated some extremely handsome men in my life, truth be told, 9 times out of 10, they are absolute pain in the ass. More difficult, more selfish, more used to playing the field, etc. These are more stressful relationships.
Having just been pretty hurt by a guy who so gorgeous yet SOOOO childish and selfish, if a less handsome man came along where I knew I'd have peace and stability, I would now consider it. If it means I get less in looks but stronger love, devotion, and peace of mind, it's a smart compromise.
Beauty is only skin deep, beneath it could lie a wretched creature. Obviously there's something special about her if he's willing to go for someone less attractive than another woman. I typically approach women that would be considered 6-7's because I feel like they make up for their lack of drop dead beauty with a great personality.
I would question the girl not the guy. The woman you described sounds like a gold digger. So lets see what we have here. Good looking guy marries someone who's fat, ugly, uneducated and dishonest? Now it seems like this ''Guy'' doesn't care about looks, weight or honesty? Whereas the Girl only cares about money. Ask yourself this if he wasn't a lawyer would she still be interested in him?
