I've been in school now for about two weeks. On the first day I walked into one of my classes and noticed this girl eyeing me right off the bat. So, I started flirting back with her. Things were pretty good. She was almost always looking/staring at me and she is always trying to be near me whenever possible. So, a couple days ago I decided to ask her to go out to lunch with me. When I asked her, she sort of looked away and like mumbled that her friend wouldn't like it. So, i told her that her friend could go without her for a day and that she should come out with me. Anyways, she nvr showed up and I dont know why. I'm not sure if she is interested or not. Whats the deal? Should I ask her to go out again. Ever since that day, which was only a few days ago, I noticed that she is starign less and she doesnt seem as interested, but she still gives me a look every once in a while. What should I do next and what should I have done?
