Um guys I actually need help???

Okay so I would appreciate it if you guys could bear with me, read through this, and give me some advice as to what I should do.

Background info: So there’s this girl I know, and she considers me a friend. I talked to her before, but I realized a tad bit too late that i really don’t want to be friends with her. We did message and we hung out once but soon after I quickly realized my mistake.

I am 98% positive that she has a crush on me. A serious crush. She follows me around everywhere and messages me on Facebook 2+ times a day. (I don’t respond to them until I know she’s asleep so we don’t have to have a conversation.) She is not getting the message. And, she asks me things like “why don’t you respond to me?” and “do you not like talking to me?” and I cannot say anything rude.

I have a feeling that she will cry if I tell her that I don’t want to talk to her anymore. She cried when her badminton coach told her she had a chance of being cut from the team (she wasn’t though). I’m not mean enough to just tell her to fuck off, but I don’t see any other way to do it.

The thing is, now I don’t know how to stop talking to her..??? I have legit tried everything. I ignore her messages. I don’t look at her, ever. I never make eye contact with her. I try to talk to other people while walking with her in the hallway. When I do talk to her or respond to messages I use short, concise responses.

I have run out of ideas. How do I get her to stop talking to me, without hurting her feelings?
