She may think you might make a good boyfriend, but you're far too valuable to her as a friend for her to risk plucking you out of the friend zone (what if it didn't work out and she lost all that value you provide to her as her friend?). She may think you might make a lusty secret lover, but if she goes to bed with you she might risk losing all those great party connections you always provide her if you get jealous or there's a fight... better not to risk her party connections, which are a lot harder to come by, for some sex - which is comparatively easy to come by. And lesson number one about getting girls is, because sex is so damn common, if you have anything else to offer her, she's going to drop kick sex far out of the picture until she has that other thing secured first.
