Is she interested in me?

So I went out with this girl and it went great. After the date she got my number and even texted me first a couple days later. I invited her to a Halloween party the following weekend and she said she was down to go. On the day of she cancelled on me and said she still wants to see me and hopes I still want to see her too. I told her that is fine and to let me know when she is free to meetup again. She left that message on read and I haven’t heard from her since, but she still likes all my instagram stories so I’m a bit confused if she is interested or not.
