I'd just give you one piece of advice (unrequested of course but needed nonetheless):

Behave like an adult instead of a college kid.

You changed your own rate, you accepted whatever conditions she places and off you went on your merry way to enjoy your break.

The person who was going to hire you needed to talk to you while you were gone, and you didnt respond in time, so she found someone else.

It was her wedding event, she was doing her job, and I really do not think that venting and badmouthing her for your own miscalculation is plain wrong.

Feel free to flog me if you will, just the way I see it.

I've hired people in the past, and often had similar situations where I've had changes or questions and they were unreachable so I went with someone else.

Such is the real world workforce.
