My crush is a bitch but I still like her.

Long story short:
I fell for her, she would always text, message and asked me to be her girlfriend.

Then a couple of months ago, she stopped talking to me. Totally. I tried to get in contact, and she'd ignore it. I finally talked to her the other day, but she was distant. I asked if things had changed and she said they hadn't but I think something is up.

After I fell for her and she ignored me, it makes me feel like shit and I feel worthless, like it was my fault. Like I did something.

I'm angry at how she's been treating me, but I still like her. I wanted to get angry when I talked to her but I couldn't. I couldn't bring myself to say the things I wanted to.

I know she's having a hard to of it atm, and I don't want to add to those problems, but she's treating me horribly. I wish I could just walk away, but I can't.

Should I wait it out? Or move on? what happens if I can't move on? I don't want to, but I hate how she's been treating me.
Has anyone had this happen to them?
Thanks.
