I don't know what to do plz help?

i like 3 different girls. one of them ive already asked out and she had a boyfriend, but not anymore, the other i kinda know and when i flirt with her she plays hard to get, and the third is a junior (i am a freshmen.) and she is in ELD (only knows spanish) (i know spanish but not much) one time i brought my guitar and she was feeling it (i carved an aztec calender on the back) and i looked at her and smiled and she smied too but maybe she was jus being nice. which one do you think i should go for?
