I like this girl ALOT(please help)?

Ive seen this girl for 3 months finally got the nerve to talk to her. Now we talk everyday on myspace. i told her i thought seh was cute and she blushed. we flirt and she just is so perfect, im a dom(boy in the reltaionship) i dress in boys clothes and everything sometimes seh says she thinks of me as a guys. idk what to really do.....i like her alot but dont wanna ruin our friendship. im a senior she s sophmore and im thinking about getting a rose on my last day of school(friday) and handing it to her and when she asks why say just because.....what should i do
