Does she like me? I'm really cunfused?

Ok so there's this girl that I've known for ever. And whenever I see her she always punches me in the arm. And then we had a ceramic class togeather and she came and talked to me every day and gave me her number and hugged me every time she saw me. And said she wanted to hang out but one day she just stoped talking to me and didn't hug me anymore, we never hung out. I have no idea on what I did or said to her
