She was unamused and told me to reschedule.
Why do you think that she was so adamant about rescheduling?
I think it's because she doesn't want to hang out with me
Did you give her a trivial reason for not showing up? You can't blame her for being annoyed that you treated you appointment with her like it didn't matter.
Maybe but I don't want to reschedule.
I think that you have every right to be a little upset. I get how hard it can be when someone misses an appointment with you.
