Or when they breakup with a girl, they always downgrade?
Most Helpful Guy
Because pretty girls are sometimes time wasters, high maintenance, trouble makers, play hard to get, beat around the bush, and they can get away with it because they are pretty. They are more demanding and some of them, not all of them have a shitty personality.
Meanwhile an ugly girl tends to be outgoing, she knows she isn't so pretty so she doesn't play hard to get or beat around the bush, some has a great personality for lack of looks.
Men put value on women, and men won't court an ugly girl for a long time, it's just not worth effort, time and money. Women know this so ugly women won't make him waste time otherwise she risk to lose this potential partner.1
