Is this my stupid anxiety brain?

So my girlfriend is doing college right now. It lets out around nine thirty at the latest. We usually call and talk on the phone at night before bed. I messaged her at 9:40, saying I hope her class went well. She then told me she couldn't talk tonight because she was in the middle of cleaning. Then could talk if I didn't mind background noise. Wait, no, now she can't talk because she's going to nap. Am I just anxious? Something just doesn't feel right to me.

I guess her not saying anything is what really bothers me. She was just going to not let me know I guess.
