I've been following the thread, and have been hesitant to post. Mainly because of replying comments. But I need to bring another scenario to this lifestyle commentary.
The little stuff.
If I ask, what do you want for dinner, what/where would you like to eat... if I get a question back, there is no further conversation, I make the decision. If I'm asked, I do not reply with a question I tell where/what I want to eat.
The BIG stuff...
Roofing the house, buying a car, an addition to the house, vacation...
We have a household account we both pay into (utilities, repairs). We each have separate bank/investment accounts. However, if she wants a new roof, a new car, steak and lobster for dinner, she pays for it, I do not question it. This last summer, I wanted an outdoor kitchen, she gave me $2000 for my kitchen, she doesn't ask where in the processes the project is. A few days ago she wanted a BMW X5 instead of an Audi even though I wanted a very cool Jeep, she got the BMW.
We have no arguments about "what to do", maybe if each other really hated the decision, we discuss it for 5 minutes after, but the deal is done and delivered. I wonder how many people are in this situation.
I have been married for 107 years.
