So I had a date with a hot girl about month ago, then she cancelled a couple of days before ('something came up'), so I said 'well, I'll see if I'm free another day'. Last week I text-flirted with her a bit and set up a date for tonight.

This evening, I stepped out of the shower to a text message saying 'I'm tired so I'm staying in tonight'. What the fuck! She was the one who first came on to me!

I called her and got her answer phone and left her saying a message saying call me back. But seriously! What did I do wrong?

EDIT: She just called back, she sounded genuinely tired (she started work at 6.30am and it was me who 'imposed the time of the date), so I told her to give me a ring next week and I'd see if I was free. I've already set up a couple of other dates with girls just to try to kick off the one-itis that I can feel, but any advice on how to proceed would be useful.
