There is a thread on this topic.
I have personally found ugly women to be a bit bitchy. And I include 40 plus women in this category. Some have an attitude like a virgin yet. Many date numerous men and make sure men find each other and fight. For this, they feel entitlement and make sure everybody knows that guys fight over them. If you want woman to marry, marry a beautiful woman than marry on average and expect her to be good just because of her looks.
