Am i just another friend?

I find her extemely gorgeous, and i just dont know what to do.. my friend said she thought i was cute.. but idk anymore. She joined my class and weve been joking around, shes slapped me on the back of my neck (jokingly) saying im so funny,is always staring at me, she comments and likes my statuses on facebook, and shes always touchy feely, and today we were working on computers, and she yelled my name from across the room, and she did that heart shape garbage with her hands, and i ignored her, and when i walked up to her, she said "oh so now your talking to me?" , but then when i was walking during lunch, she pointed at me with one of her gf, and i walked up to her and i was like whyd u point at me, and she said i was just telling my friend that your my buddy, another day though i saw her walking alone ,and i decided to go up to her and conversate, we just kept walking not much said.. so i kinda lost all feelings i had for her.. im lost ... :(
