I honestly do believe that pretty women tend to be slightly more crazy due to this. Rich men also have this problem but it is easier to hide being rich in the beginning of a relationship but if you are pretty without makeup it is hard to hide.

I think the slightly-better-than-average-looking women have it easiest out of all women

I agree it can be hard because most guys will hit on you like its a game/bet/challenge to see how far they will get. There's no real intention/purpose because they don't believe you would actually be interested in them.
Then with other guys, they won't even attempt to get to know you because they believe you're already taken or you're a gold digger or stuck up/high maintenance, you're out of their league & would never be interested in them. Some will fear that you're being nice to use them. It's crazy the things some of these guys come up with.
What I've noticed about guys like this, they aren't my type and we're better off being friends. Most of them never get over their insecurities & that's when the jealousy manifests.
