Girls, Why does she act strange?

there is this girl I know who always seems to ignore me in class and is a social butterfly but recently I notice she glances at me 1 or 2 times during the class and the other day she said to her freind he is leaving as i left and she barely even knows me and finally I walked past with a freind of mine and when she saw me she hugged her best freind for like a whole minute. does she like me hate me or is she conflicted or is it all just chance?
