So theres this girl... Does she like me ?

Im your everyday smooth/cool guy.. So during the summer i was at work (skating rink) This girl comes in with her cousin whom im cool with anyways she said i was cute (her cousin told me this). Skip to school, so school just started and she goes to my school, and she often gives me these Stares(mugs) me. The catch is She has a Boyfriend whom is always mugging as if he knows she likes me and the other day when i questioned him "Why you be mugging me" he tried to fight me (to impress her) but never did anything to me when i squared up (i've tried to fight him 400 times prior to this and he was always scared lol). So i have 2nd pd with her she she looks at me often and everyday after class she walks slow/looks at me as if she wants me to talk to her or some (her next class is beside mines) one day in 2PD i finished my work and had my head down the teacher came over and said: are you okay man, me: yeah, then he says "oh btw i think there trying to get your attention or something over there<<" and when i turned and looked (slow and smoothly) her/the guy beside her/the girl behind her was all looking at me prior to this i think she had asked the guy beside her What my name was or something like that for the record i don't think he knows it (today she heard a different teacher say my name) so ik she knows it if she didnt. Yestarday i walked past her up the staircase she mumbled something which i think was "OMG" as if "Omg he's so fine" or something.
