What exactly does this girl want? could she be interested?

I'm bi, and the girl I really like is a lesbian. I accidentally sent her a txt that was suppose to go to my cuz that said are u going out sat night. I realized I sent it to her and I was like sorry, my bad. She said your good lol! I told her a few days before this that I was going to stop txting her and leave her alone. So Then I was like I just wanted u to know I'm sticking to what I told u that I'd stop txting u. She replied and said you can txt me, but I haven't had my phone lately. Then I said i feel like i'm getting on your nerves txting u especially since I always txt u first. She was like naw i'm just shy plus this summer been crazy! Then I told her what my friend told me which was that I shouldn't txt people cause if they wanted to talk they'd txt u. She was like no I want to talk to u and kick it and what not. Then I asked her if she was going to be at the club saturday night and she was like yeah. I txted her saturday while I was at the club and asked if she was there she like no I stayed home tonight. Then after that I sent her a txt that said I know your not feeling me like i'm feeling you, so I'm just going to leave you alone and of course, I haven't heard anything. I feel like an idiot being depressed over a girl who doesn't like me. A girl I don't know that well that I had a class with in the spring. She just got out of a lomg relationship. My thing is I asked her straight out before if I even had a chance she didn't even answer me. What's her deal??? If she isn't interested in me why doesn't she just come out and tell me. And y say she wants to talk to me and kick it if she doesn't, and if she makes no effort too?? I don't get it! I just REALLY like this girl A LOT!!!
