I need relationship advice?High schooler?

I am a freshman in highschool and i need some relationship advice. There is a girl at my school that is super cute and super nice, down to earth, kinda all round nice girl, and i seem to like her, and it seems she likes me. Also, is this flirting: She play around hits me, she calls mine name out loud when she sees me down the hall, she hugs me when ever she gets the chance, and she smiles whenever i am around. She has called me up out of nowhere to go to a basketball game to hang out with her and her friends(all girls) then at the basketball game she invites me to her new years eve party. Now she has a boyfriend and has had him for a month or two but he goes to a school that is a long way away from her. Does she like me or is she just being a girl and flirting with me?

just flirting, maybe she liked you but you got to make a move first let her know how you feel.
