<human>: Can you provide a brief rundown of the text in within 3 sentences?

A few weeks ago I met a girl, got a kiss in, got her number and arranged to meet up with her. The day before I was supposed to see her, I realised I'd neglected to give/ask for a time so I messaged her to find out.

Got a reply hours later asking if it's ok to postpone because she had an exam she needed to study for the next week. I said sure, let me know when you're free and she said she had exams for another couple of weeks (now finished)

On Saturday night, I was out and texted her saying if she's in the city we should catch up. She said she was staying in, maybe next week. Replied to say ok, will arrange something during the week.

That's where I am now. I will arrange something during the week but does this seem like a waste of time?

What's confusing me is the list of possible outcomes in my head when I messaged her:

1. no reply

2. no

3. yes

4. no, but... (which is what I got)

If she wasn't interested, would she bother replying or saying no, but...
<bot>: met girl, arranged date, postponed, attempted to arrange again and was told, no, what about next week?  Wasting my time?
