Does she like me what does she mean?

hey so i have this girl that ive met recently she's 20 and been folowing me kinda well we work together and on our 3 hour brake she asked me if i wanna get some food from chowhall then she asked me if i wanna go to her barracks room and watch a movie with her alone in a room so we did, and now i was wondering did she meant anything by all that did she tried to make a move or expected something from me and if she did is it too late now? and how should i ask her?
