Theres this girl at my school.?

I'm 13 and ive known this girl for around 3-4 years, I really like her, but she doesn't really feel the same way, I'm kind of a computer geek, Anyway (i don't know if this would help but) she calls me squishy and i get alot of hugs, and ya but everyone calls her Fluffy and pokes her alot. (and also she knows I love her... she's also 1 year older than me but i don't know if that makes any difference...)
