Really confused?

Not sure what to think, Everytime I approach this girl to talk, she's noticeably different to how she acts with others, for example Everytime I talk to her, there is this sudden character change and she becomes a lot quieter and barely says anything (she's usually very bubbly and confident with other people) I've noticed that she often looks at me and it's multiple times a night, sometimes she's confident enough to hold eye contact with me, sometimes averts her gaze, she also speaks with a really quiet voice but with other people her voice is normal (she's usually pretty loud). I've seen her lowering her head when she's walking past me and sometimes Compresses her lips, Does She hate me? I'm really confused
