Question for everyone.... Why is your money their money and their money is their money?

I've been married for 36 years. Worked hard to provide for my family. My wife also worked. I nver asked how much do she make, never saw nor asked to see her pay stub, never suggested nor said anything about what she do with her money. I picked up a second job, so I could have some spending money of my own. Now! My wife is trying to tell my how to spend it. What is with women and the need to conrol other people money?
