Did she lose interest after we hung out?

I hung out with a girl from work this past Saturday. Before this, she was really friendly with me at work and would seek me out to talk, joke around, smile, and gave me her phone number to hang out.

We went to the movies and she got pretty physical with me. She held onto my arm, we leaned into each other, and there was some arm and hand touching after the movie too. I didn’t kiss her or make a bigger move because i only met her recently and wanted to take things slowly.

The next day at work, she seemed quieter than usual and didn’t really seek me out like she normally does. She still joked with me a little when I went up to her, but the energy felt different from before. That night I texted her saying I had a great time and asked if she was free again this week. She said she had a good time too, mentioned something from the movie, and said she “should be.” I told her to let me know when she’s free and she said she would.

The day after that, she texted me asking for my Instagram and we added each other. She still hasn’t given me a specific time to hang out again though, so I’m confused.

Does this sound like she lost interest after the hangout, or could she just be awkward because it got more romantic than expected? Maybe she thinks I don't like her like that?
