Step back a sec...remember your wife is a WAS...she will use everything to justify her decision and make you look like the bad guy.
YOU ARE NOT.
You just reacted to her, she knows that will get you angry...you gotta stop reacting to her when she pushes you.
She says that again...respond calmly with, I am sorry you feel that way, but that was not my intention to upset you, but in reality, we could not afford to go to Flordia right now.
Respond like that, she won't know what to say, there is no argument. She tries to push you, end the call politely.
