Gurl crushh

Guys idk what to do, I think I have a crush on a girl. She goes to my school and she has long brown hair and beautiful eyes. I always think about her and try making myself look better( for her if idkkk) I like seeing her at school, she always greets me with a smile that’s what I admire about her because at school I’m moody and don’t smile, I have fake friends that don’t even care about me but it seems like she does. Recently I found out we go to the same volleyball club bc I met her there ofc I was really excited and didn’t know what to do, do I shake her hand, hug her , but we weren’t great friends we barely know each other but the sad thing is is that she has a girlfriend and she’s open about it. She’s very brave that’s what I admire about her. I’m just hoping we can become better friends and stay close. But I don’t think I’m a lesbian bcs i do have male crushes but just not my age bc theyre so gross like how can somone like a dirty rat ew but like celebs and ficition men are 😩 So guys what do you think my sexuality is?
