Situation: Cute virgin, shy girl, totally not my type for any kind of relationship other than friends. We used to go to the same HS, now I'm at university. We haven't even talked more than probably 2 sentences, but she is my facebook friend anyway. It all started when I put a status about my mom pissing me off(she is basically conflating all over the place and kind of thinks that I fuck every girl I speak with, which is pretty annoying. But that's not the point here). So she messages me about how her mom pisses her off all the time too. Typical teenage problems. When I find out she's a virgin I instantly know that I do not want anything from this girl.
I talked with her about many different things. School, Family, Friends for first. Then more interesting things like some spiritual shit, effectively remembering and controlling own dreams(damn she's so naive she bought all my shit without question...) HOWEVER... I made sure that sexuality is avoided as much as possible, and I even stated it clearly that I have a no-no policy against virgin girls. Of course... it's in my personality. I couldn't help but flirt a bit but it was very innocent. Commenting on her using way too much

smilies and things like this.
I also met up with her once. I made sure to demonstrate EVERYTHING that I know doesn't match for her. I talked about my drunk stories(she doesn't like drinking), I talked about how outgoing and social I am(she doesn't really like people and going out generally). How much I tolerate every dick-head(she hates and despises of people who she views as unintelligent) and what a good relationship I have with my ex girlfriend(she never had a boyfriend before). I was literally ANTI-GAMING her.
And it blows my mind away that she just doesn't get off me. She messages me everyday. She tells me lines like this: "I hope it's not a bother that I'm writing to you, but talking to you just makes me feel so good"
Seriously... what is wrong with this woman? I know it's a strange question but why does it work what shouldn't? I basically kicked every PUA principle in the balls. I lacked sexual tension and escalation, I didn't apply push-pull theory at all. I demonstrated values which she should find unattractive. I didn't (or at least intentionally) create attraction, only rapport, I didn't even think about seducing. It's like I purposely wanted myself in the friend-zone. The only values that she can find attractive about me are these: interesting, funny, nice(yeah... I was fucking NICE to her all the way), intelligent. And we have some things in common e.g. she too wants to come to a med. school. Is this enough? Were all my attempts in vain just because of the person I became from pick-up and the unfortunate things we have in common(annoying parents, med school plans, similar music and pet tastes, similar thinking about politics and education)?
Really guys... I want to keep her as a friend because she's a very nice girl, and I like nice girls as friends, so I don't want to tell her to just fuck off. If I knew the cause of this maybe I could just do something about it. (Oh... she's not the type that if I don't make a move she'll just move on and find another guy any time soon. I know that from a story she told me...)
