Most Helpful Girl
I've only ever asked a guy what he wanted from me because I've been intimidated. It's more of a "you're so out of my league why are you talking to me" kind of thing. Maybe she was just confused as to why you were being so friendly, most guys only really buy drinks in hope to score, unless you weren't. Maybe the whole buying her a drink and checking her out was giving her mixed signals. Try talking to her in a different environment other than a bar!
