TITLE: I [M15] need help with getting a girl [15F] who has a HUGE crush on me to leave me alone.
POST: I met this girl (let's call her T) in class a few weeks back when she started sitting beside me.  We talked a lot and became friends but being a guy I totally missed that she had a crush on me until one of my good friends that knows her as well told me that she does.  And apparently its pretty intense. I dont like T in that way at all and now I'm not even sure I want to be friends.  T has also told my good friend that T thinks I like her back and that we are close to dating. I think T thinks this because I may have accidentally led her on because this is the first time a girl has flirted with me first so I didn't know how to react.  Somehow T got the idea that me and my close friend were dating because we went to a movie together as friends and when T found out she hit my good friend and told her to keep her distance. So basically I want this girl to leave me alone but I dont know how to tell her that or what I should do to accomplish this. Thanks in advance!
TL;DR: 
met a girl. She likes me a LOT. I dont like her. She's getting a bit crazy. Need help getting rid of her.
