First reply nailed it!
As you seem to be after more details, OP:
I did not agree to obey and I got married 30 years ago. I’m not going to trust someone else’s judgement over my own as I think that’s a dangerous road to go down. Nor do I expect him to obey me. So that’s in not in the job description.
Things being a wife has been to me over all the years -
Supporting him in the less good times - when he’s had operations or health issues I’ve been there for him, prioritised visiting him in hospital, looked after him when he’s got out. And he’s done the same for me. We’ve both had some major health scares and sticking by each other has been paramount. Sometimes we haven’t even known if those health isssues will ever get better, but we’ve hung in there and been there for each other, finding the good bits through the bad. Same through employment difficulties. Neither of us have taken advantage of the other’s earning power but both of us have leant on the other financially through difficult periods.
I think, in short, being there by each other for the ups and downs. My mum always used to say “row the boat together as you get there easier that way”. It’s good advice.
What I think a wife ISN’T - someone to take on an unequal burden of life’s difficulties, chores and work. Someone tied to a life of drudgery and unhappiness. Someone to put up with disrespect. Being a wife shouldn’t be those things. That doesn’t mean you have to do the same jobs round the house. But it must be equal work, however, you work that out.
Mainly, being a wife should be huge fun. Lots of laughs, lots of enjoyment. Shared goals and shared happiness.
Everything that applies to being a wife, in my opinion, also applies to being a husband, and also to both parties of a same sex couple.
