Why did she say no?

Anonymous
I started getting feelings for this girl in a couple of my classes. We talked a lot and she would even come over to me and start conversations whenever I wasn't with anybody. she always played with her hair and we stared into each others eyes when we talked. my girl friends all told me to go for it so I did. she told me that she needed to think about. well she never said anything to me and never gave me an answer. we didn't really talk that much after that and now a month later she is flirty. when I helped her with her books she grabbed my arms, started blushing and all she could say was wow. she starts these little conversations in the halls and is very smiley. Why would she say no then but now flirt with me a lot?
