The stark reality and actually seeing it on paper with income next to outgo broken down into what it costs just to live can slow things down a bit. I'm not suggesting that this will suddenly make her want to work on the marriage but it may give you both time to calm down even more and be able to work together.
Truthfully, I can't even imagine how I would be in trying to work money stuff out with my H without a third party present. I would want/need someone to keep us on track.
Why do you think she said that about your family? Can you put yourself in her place for a minute?

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
