I'm getting mixed signals from a girl that may or may not like me. I do like her so I don't know how to react.?

I've known a girl that use to work with me in a store since October. I believe since then we've grown quite close over the year especially in the recent months.

I realised about this girl is she has a bubble personality. Like she would flirt with people but not in a serious way and I haven't let that affect me.

Over the last few months things just picked up. Literally she started telling people in the store we worked at "were dating" and when she did resign she gave her reason as dating me. shortly after she changed it. She also loved to take picture with me. The way she took pictures with me wasn't how she'd do it with anyone else. She'd edit my pictures on snapchats with love hearts and even wrote "my girlfriend" and stuff. These things weren't done with anyone else.

I thought maybe I'd ask her to hangout just the two of us, we were good on it but my first plan she changed her mind last minute and would make up excuses to not go out together as the two of us in terms of hanging out so I've just stopped asking.

I don't know where to go from here. Should I walk away for good and just be friends. Should I confront her and see what she really wants?
