There's this beautiful, brilliant girl in acting class that I really like

. She's everything I've ever wanted in a girl and even a little more. But I feel as though she's on a higher level then me and if I upproached her I'd ruin our semi-friendship :/. It's not like she's snobby, oh no she's very nice. I just think she's a lot better then me and asking her out or something wouldn't be a good idea, but I really like her. What do I do

?
PS. All idiots ( payne, mad max, etc. ) will be ignored and most likely laughed at.
