One thing I didn't mention in my post, because it just occurred to me after posting, was that I never honestly told that girl how I really felt about her. I think I thought it would scare her off. As it turned out I never got the chance to tell her.
Some women are fucked up. But they are also incredibly insecure. maybe she's testing to see how you really feel.
You could tell her to her face what you've expressed in your post "There's just something about you..., her passion, etc". That was passion coming from you.
Christ if that doesn't work nothing will. Best of luck mate
