Girls, i need some help with this girl?

Ok, im going into freshmen year, and me and this girl have been flirting in school ever since probably april. weve flirting occasionally but sometimes she just goes and talks to other guys. idk if shes trying to make me jealous or not but i like her and wanna ask her out but she hasnt really showed any big signs of liking me. But when school was still in we would be sitting and talking and people would be like oh yeaa and stuff and she'd say like 'yea we're dating now' and stuff even though we obviously werent. so does she like me or not
