That's exactly the term I would use as well Linda. It sure does sound like she ditched you to go off and do something else without even a call or email to say plans had changed. She did know you were driving 2 hours, right? Sounds rather inconsiderate to me, and I am angry on your behalf.
And here you were - worried about her!
I wish you lots of luck finding a more responsible, considerate person to work with, and lots of "good puppy vibes" also. Your daughter is quite a cutie, and I would hate to see her disappointed again.
