Sorry, I forgot to add - a good freezer is your friend.
So cook good food, but do a double or triple batch of a curry, say, as it's almost no extra work but you can freeze another couple of nights dinners. Reheat sauce while cooking fresh rice, and occasional stir as you get clothes from washing machine to tumble dryer and check post and make beds and sweep floor.....
When you buy food, get things like GOOD sauces and don't worry about using them when they have good ingredients.
Do things like roast veggies with a roast dinner (courgette, pepper, onion, garlic, tomatoes etc all in small dice, well seasoned and olive oiled) - leftovers freezer well and work great just tossed over freshly cooked pasta or mixed into tomato sauce (can hav bacon pieces, chopped naice sausages, diced chicken or prawns as "meat" if needed in it). Proper pasta if using meat, or just fresh pasta which cooks in just a couple of minutes.
Also learn how to set up your oven on the timer, so putting dinner into it in the morning but timed to turn itself on and cook, ready just as you are due home or within 20 mins or whatever suits.
Garden - find a local teenager. And make it low maintenance over time - so it only needs minimal weeding/watering etc on occasion (while the curry etc is cooking?).
Car - get it valeted every 6 months, bring through carwash when getting petrol maybe every month if its bad but use that time to make phonecalls, write cheques, or just read a magazine...
You only need to iron for yourself, and lots of modern very good office wear needs no ironing at alL!!
Put on a load of laundry in the morning as you leave for work, pop it into the tumble dryer (or on line) when you get home, put into a clean basket once done and sit yourself in front of a favourite tv programme or movie once a week and fold it all then. Laundry is clean to use if needed in emergency, but it's not such a chore to fold that way.
Alternate internet shopping with a major supermarket one week (getting cleaning stuff, stores stuff etc for 2-3 weeks as well as weekly fresh stuff), with using local shops next week (butcher, Fruit and veg shop, nice deli etc), and use that local week to do things like post office trips (stamps, pay bills, etc), visit library, go to chemist.....
I work hard to keep all the balls in the air, lots of juggling required, from the outside I've had people say it looks controlled but its not inside it all. And that is with DH on board.
You can't do it all yourself. DH needs to be an equal part of the partnership. And external help may be needed for some parts (cleaning, gardening, ironing, cleaning car, cooking (good ready meals or takeaways etc), grooming....).
