Forget the four easy steps, forget the knee-jerk divorce her ass, you have bigger problems. The mere fact that you would write a post like that means that there is some fundamental breakdown in your communication with your wife. I have a hard time believing she doesn’t know what you make and roughly what your assets are, so that isn’t it.
Sure you can take the engineers approach, write down the numbers and make a logical argument. Of course if you could do that, I doubt you would have written this post. Even if you had it would probably be an entreaty for substantiating facts, not a WTF am I going to do situation.
Maybe a divorce is your best option, or even discussing the idea. Until there is more information on what the real roadblock is everyone here is going to give you typical analytics or gut level reactions. My personal favorites are the gut level reactions, but thats just me.
I have yet to meet a woman who makes the most important decisions in her life (job, housing, etc) in what I would consider a logical fashion. What do ya know, stereotypes are a handy time saver! I have yet to date a woman that I allowed to overpower my rationality with her judgment, but again thats just me. I’m an engineer.
