Even though my wife worked for part of our marriage I always handled the money. This was never a problem.
Let's see, since being widowed for 50 years and I earned all the money, I guess you could say the money was womanhandled instead of manhandled. This was never a problem.
I've always had my own bank account, separate from the household account. My husband pays the bills but we both have access to all accounts so there are no secrets and no one "controls" the finances.
One banking account for the both of us. Since she is a degreed accountant (2-AA's/1-Bachelors), and has all of the job experience in finance and accounting, she does it all. However, I do all of the online buying. My former job in Purchasing, really never ended. But we met, I handled all of my finances. Sometimes I had a savings account and other times not. For those 22 years of being divorced/single, I paid cash for everything.
Always me. He is easily frustrated with these things . For one he is dyslexic and not computer person. Never a problem.
For me it was the purchase of Long Term Care Insurance when I retired. It has saved and will continue to save my other assets and resources from being exhausted.
Hanging onto the house when we split up just 90 days after buying it, and I was only making $5/hour. Times were tight. The area started to really grow shortly after that, my pre-tax mortgage was soon cheaper than apartment rent, and the house ended up being a big chunk of my nest egg. I guess resisting the urge to continuously "trade up" as so many around me did was my second best financial decision. A 600 ft² home can be very efficient.
