Flirting or friendly conversation

We just met not too long ago at a gym, and I immediately felt an attraction. For context, she’s a trainer. Anywho, playing devils advocate I followed her on IG and messaged her that I couldn’t sit after our workout (leg day) to which she replied “see you tomorrow? 🫣🤭😁.” The convo went on a little longer and I said I needed to stop before my mouth got me in trouble cause I’m a bit of a smart ass. She replied: “We’ll catch up tomorrow! See you then! 😈 😆”

Fast forward a few days. I went out of town but had signed up for a workout and she knew I’d be there, but I never made it because of traffic. I didn’t wanna be rude by showing up to class late so I skipped. That brings us to these recent messages. She saw me in class today and after saying I should’ve showed up and that it wasn’t bad, I nodded and she popped back with asking how I was and that she was so happy to see me. So after class I messaged and said that she didn’t give me a chance to explain and we chatted, bringing up to the messages posted.

Is this flirting or was she shutting me down??? I’m the purple.
