Thoughs on this girl and her sudden change around me?

she appeared around here this summer as she worked at a restaurant that i went to.

anyways she mostly ignored me during June/July , i'd notice her at bar and get no re action , she didn't even seem that comfortable around me. i'd also check her out a lot at the place she worked as she's cute/brun type with a nice body

but a couple weeks ago was a sudden change in her behaviour around me , one night got this crazy hot look from her at the bar and she suddenly started to talk to me

now we've started to talk some more and seem to get along fairly well. was even a picture of us taken together at bar. as they have a photographer go around some nights and take photo's. i gave her my # so she could send me a photo of it , see if i ever get anything from her

she only works at that place for the summer then has to return to school in another city.

note she also doesn't appear to actually be single either is pictures on her social media with a guy , at the bar she hangs around people from her work that like to party , perhaps she just likes to go out and chill , which makes me question her actions even more?
