I don’t get it?

I’m 33M I recently matched with a great 29f woman on a dating app. We went on a date, it went phenomenal! She initiated kissing me even and cuddled up to me on a bench while we talked more. She told me how great of a time she had and that she absolutely wanted to see me again! She let me know she had a busy week and would be out of town the next weekend but now has officially given me the full ghost after being out of town? Hard to understand especially hitting it off so much. What am I not seeing or understanding?
