<human>: Could you distill the essence of the text into 1-3 sentences?

We have had some excellent dates and I thought things were going really well. Last weekend she said she was free on Saturday and we should figure out something to do. Suddenly yesterday she forgot about plans she had. She said she was busy and didn't suggest a different time. When I asked if friday would work I also mentored I am pretty free next week, giving her multiple options and I haven't heard back from her. We have been texting for about a month now and usually she responds within an hour. It's been more than a day. How should I approach this? What should I say? Maybe she didn't see the message and she is really busy. How do I not sound desperate at this point?
<bot>: I need advice on how to not sound desperate when asking a girl I have been dating if she is available to get together.
