I think she probably does like you..... but..... a definite way to get her to back away is to go up to her and ask her directly. She will feel embarrassed and put on the spot and not know what she should say. So, I suggest you don't ask her directly anymore. If you fancy her do, as the above poster suggested, ask her to meet for a coffee (or whatever) something light and casual. Talk to her in a friendly manner without any pressure put upon her....then either ask her out or start texting with her at least and see what kind of response you get from that. Best of luck.
