I Cant Get Over This Girl?

I like this girl alot. We're pretty good friends which is great! but i want 2 b more than that. I've nvr liked a grl lik this . Sure there hav been girls b4 her that i likd. but not this way. She doesnt lik me bac and just wants 2 b friends and i respect that and ive tried 2 get over her. But every time i c her or hear her tlk im right back 2 wer i started. I cant help it. Its hard 2 get ovr her and i rlly try 2. I dnt know wat 2 do. Ive even tried the whole, "Dont tlk 2 her and she'll go 2 u." That just makes things worse lol.
