Michelle routinely helps me in the shop when I ask her. She helped wire under the dash, and will hand me tools when I'm lying on my back. We put the motor and trans in together. She always helps me with brake bleeds too. The help is very much appreciated.
As to the finances, we have multiple accounts. We have a joint house account and individuals also. And like Stan, what's mine is Michelle's and vice-versa. I always share how much I'm spending on stuff, but like Stan, as long as the bus keeps going, she doesn't concern herself with the details.
When I retired, I had been looking at Caymans for a year. When I showed her the one that I eventually bought, she said "Why don't you buy that? You deserve a retirement gift to yourself."
That right there is gold. Pure gold.
