Look ... there are far more stories about dating crazy women than there are stories about dating not-so-crazy women. The crazies are just more visible. And they've dated more guys.
That said, your reason No. 1 holds up pretty well for a lot of people, though it's soooo not just guys who want to "fix" girls.
If we are talking about something more than a one night stand, I think it has to do with making the girl happy. Most guys like it when they can make a girl happy. I think it becomes a challenge to make the crazy girl happy (for a moment). Because it was so difficult to make her happy, it becomes like gambling, you just keep trying in the hopes you'll win again.
I know so many men who marry the crazy chick in some futile effort to make her happy. Three years and 1-2 kids later, they are miserable and can't figure out why their wife is never happy. Here's a hint boys...she can't *ever* be happy. Once happiness enters the equation, craziness must follow.
Stick with the non-crazy girls (who can be just as crazy in the bedroom) who are happy when you do little things.
Spent part of my weekend with a lunatic, and as you'd expect, she was the one who went home with a fellow. Maybe he thought he could fix her, or maybe he likes blondes. I don't know. But I wouldn't wish that mess on Bernie Madoff.
