Recently, I asked a young woman from my course out. She happily said yes, suggested a place, gave me her number.
I wrote her to arrange a time, and she responded the next morning, saying she couldn't make my suggestions and offering other dates and times. I asked her if we could do one of them.
This was yesterday and, since then, no response. We interacted well yesterday, and today she waved at me as I came in and I felt was friendly (although either she was nervous or had something on her mind).
I'm really nervous why she hasn't replied yet. My message was taking one of her suggestions, and offering a specific time.
And I'm also worried she won't reply tomorrow as well. I don't know what I should do. I could write her and slightly alter the meeting time, but then will worry if she will not respond to that, too.
