Seriously, whats with this girl?

well her and my friends (who r the same people) told me she liked me and we would flirt. Alot. we were writing notes and i ended up telling her i liked her. i asked her who she liked, but she wouldnt tell me or she would say to guess. i asked if she liked me and she said no. well mor like wrote "No!" (btw i only asked her once. so does she like me? srry if there was not enough detail.
