I've been in the same situation you were in, I told her how I felt, and waited. She and her boyfriend broke up (unrelated cause). A friend of mine asked her out right afterwards, I waited a little while, and asked her out aswell. She told us both she wanted to wait untill she was fully over her ex. I was just there for her, comforted her, told her that she was better off without him. My other friend was pushy and she told him no. She never gave me an answer, some other bloke, one who she never talked about, probably didn't even know. Asked her out and she said yes. Never giving me an answer(which means I basically got a no). Well, now she back with he frist boyfriend (the guy she was dating when I told her I liked her) and she wants to start talking to me again, so my advice is.
Move On. She doesn't like you the way you like her, she probably never will.
