Thanks. I appreciate your opinion. And I am VERY receptive to the idea that I'm overreacting.
I would just quibble that I did let my EW know that I was going out of town, and the exact dates I would be gone because that only seemed fair, and I didn't want her to come to the house and not find the dog. After she screwed me over, I found another place for the dog - I've done that a bunch, generally through paid dog-sitting services, and never told her where. This time I used a friend - but I don't see how it is any different. She would never have shown up or complained about it earlier.
