Should I just ignore her?

I have almost lost my best friend. She went to a 3 week vacation. When she came home, we made an appointment to meet each other. She ditched me, she said she was to tiered (something that I can understand seeing she had worked all night). Now its been a week, and we were supposed to reschedule today. So I told her when I was availoble. And asked when we could meet. She said we should "take it as we go" (a Norwegian expression translated directly).

I get the feeling she doesn't want to see me. I think she is mad at me, because I said I would rather hang out with another girl, because the other girl was "hot".

We have been best friends for a year.
