My DH started cooking family meals about 20 years ago when I was self employed. He said if he didn't cook we would have all starved, as I was totally absorbed in my work and hated having to stop and provide meals.
He actually enjoys cooking, which I never have. So now he does all the everyday meals, barring pies and casseroles, though he will help and prep veggies when I make them. He's a much better cook than me because he carefully watches things as they cook and times them. I can't be bothered, I just shove something in the oven and go off to do something more interesting and forget about it till I smell burning! DH makes a fabulous Sunday roast and boils dippy eggs to perfection. He draws the line at baking and cakes but we don't eat many anyway.
He also loads the dishwasher, and plans meals each week. We usually shop together and he budgets better than I do, keeps the freezer well stocked and grows vegetables in the summer. Add to that he brings me tea in bed every morning, brings in the coal for the boiler and puts the bins out every week. He's also familiar with the workings of the washing machine and dryer, and can iron perfectly well if he has to, but I usually take care of the laundry, cleaning, and changing beds etc.
I have no qualms about him managing on his own if he had to, but whether I could manage without him is another thing. But I hope that won't be for a very long time yet. He's a man in a million and I know how lucky I am to have him.
Two of our sons are also quite capable in the kitchen, but the other one lives on take-aways if DIL is away. He claims he can't find anything in the kitchen even though he built it!
