Ok so I'm 15, in high school. The first day of school I fell in love with this girl. In class I would notice she would always be staring at me. At the time she did not have a boyfriend, the staring kep on going for about two weeks then we became really good friends, then the day I was going to tell her what I felt for her, that same day she started dating one of my friends, & seems as though she still likes me! Once her boyfriend wanted to kiss her & hug her, & I was very close to them, I noticed she saw me & didn't want to kiss her boyfriend, I really don't understand what's going on or what am I supposed to do? Please help!

Ask her. Confront her and ask her what's going on. But, remember no matter what happens you need to respect her decision.

OK I'm 14, but basically this is what you have going on here... she liked you to begin with, she was staring at you to try to get your attention... I'm assumeing you weren't flirtatous enough and then you got what we call "friend zoned" you may not believe it's there, but it is and its terribal, because its very hard to understand that she is not flirting with you, but simply being friendly, you could pursue her, but I would be careful now that your friends are involved
