What did I do to bring out such a weird version of her when she is around me?

this girl isn't herself when she is around me , i've discovered she acts and dresses totally differently. the version of herself when she is around me is much more tame and doesn't wear fun or revealing clothes. but when is not around me she is not tame and fun and dresses up with her girlfriends.

she definitely isn't herself when she is around me , i've seen pictures online when she is in other places with other people and she appears totally different.

i don't know what i did , we can rule out some things as i don't send her message's online or text her , i've never seen her at the gym or in a bikini ( well in person have seen a picture ) and i've never hung out with her other than the one place we always saw each other this restaurant/pub downtown and saw her once at a nightclub during the summer a while back.
