What should I do, wife who will not compromise financially

Thank you all for your input, I will be having some serious discussions with my wife in the near future. For all of those who tried to truly grasp the situation, thank you for your time. For those who were petty or mocking of her, or me, please remember that you never know when you'll be in a situation that grows beyond what you anticipated. Life has a funny way of humbling us all.
