STR8UP, just read through this thread and went back over your original post. I'm having a hard time figuring out what you wanted out of posting it. You kind of can't fault these people for responding like they did. You didn't ask for advice, it was just a story and people are going to respond to it as they will. I had a hard time figuring out what you wanted as well.
Anyway, what I think you should do is, get the girl's phone number, get her one-on-one like you talked about in the OP, and if it turns out that you like her, then take it further. You don't have anything to lose except maybe an hour or two of your time, and like Fingz said there is no need to have any expectations.
She is attracted to you by the sounds of it. You deflected a clear sh!t test when she gave you crap about being old and dating 22-year-olds. The hard part of it is over. If her social skills are lacking too much for you to date her, then screw it and look around elsewhere. Get her phone number, set up a date with her, go out with her, and just get it over with. I can't help but feel like maybe you're making mountains out of molehills here, or like other people have suggested, just being overly-selective.
I don't think it's all that complicated of a situation.
I know how you feel, plodding through the lot of dumb chicks and trying to find the quality ones. It gets old and I get frustrated with it too. If it fails with this chick, maybe you should try targeting women who are in their mid- to late-20s or even older. I got fed up with the younger ones about two months ago and have started going after girls who are my age and even older (I'm assuming the Man Eater is in her early 20s). I've gone out on a couple dates with a girl who is almost 26, and it's definitely a lot different. Up until then, I had never even been out with a girl older than 23. I'm still open to the 21-year-olds, but they're definitely a much different breed - one that I don't think I even prefer anymore.
Something to think about I guess.
