Your doing it wrong Diana; my wife and I have had an unbreakable contract for the last 42 years, “WHATS HERS IS HERS and WHATS MINE IS HERS”.
It has worked great for our entire lives.
If I want something or need something I just tell her, and then wait for it to show up.
It’s like Christmas all year long.
Sounds like our relationship, too. Lucky us!
