I don't know what to do?

I'm in high school and I used to be very quiet. For over a year I didn't attempt to make any friends until a girl wouldn't stop trying to talk to me. I was quiet before from cases of severe bullying in the past but she was kind to me and now I'm so much less afraid of people. Her and I would spend hours together everyday. Problem is, I ended up developing feelings for her and she's a lesbian. I didn't tell her but she figured it out and she's ghosted me and wouldn't talk to me at school. I'd be fine with never talking to her again, I just don't want her to hate me as a person. Anything I could tell her to close things off nicely? Or am I better off letting it be? She means a lot to me.
