Nope, I have no thoughts, good or bad, about the poster who made that comment.
Again, I think most of you are talking about very young women. Women in their teens and 20s are notorious for this kind of behavior. The fact that the OP is in her early 20s and is bemoaning the fact that she will "foreverbealone" because she hasn't found a mate yet is ridiculous and you're right - she is looking for people to tell her that she is lovable and dateable.
When *most* women mature, they gain confidence and self-assurance. I've experienced it myself and I hear it everyday from patients as they talk about aging. We don't need others to define us, tell us we're beautiful or desirable.
Young men also lack confidence in dating relationships. Its not that the alpha males get all the girls because they treat them like ****, its because the young woman misinterprets that as confidence and power. Frankly, young men are just as guilty. I'll bet every woman here has a nice male friend who is crazy about some bitchy girl who treats him horribly. Yet he keeps going back for more.
As for the "crazy = better in bed", my male friends tell me that is only true in very young women. By the time most women are over 30, the are confident enough to feel comfortable asking for what they want and having a freer sexual experience. The crazy ones are usually fairly psychologically damaged by that time, that they become less and less attractive to potential partners. The exceptions end up on reality shows, with equally psychologically damaged males.
