Is she considering me? Is she interested?

When I first met this girl, she considered me a friend, greet me as one etc. After I told her I liked her (maybe 2-3 weeks after I met her) she stopped calling me and introducing me as friend, and started calling me by my name more. To be honest, I haven't heard her call me a friend since then. She's always teasing me about making out and whatnot. We almost kissed once (the one move I made), but she said she wanted to wait. She never seems happy when we part ways, she kind of looks sad. I'm usually keen on women, but she's a complicated one haha.
