buyer made an offer and I have accepted it but stopped replying

Buyer confirmed meet up time and place. Did not show up nor communicated that she is not pushing through in buying the book. I even gave her consideration being a student and needs the book for review, hence I agreed to meet even on a holiday. Be respectful of other’s time and effort. Goodluck to you!

Buyer asked to many questioned made an offer and promised to pay till last friday. But have not updated me since then.
