I think what she probably means is open your bloody eyes and see what needs to be done to keep your home a clean and pleasant environment.
You are a grown-up and your wife is not your nursemaid/charwoman/cook/valet.
If the loo roll runs out, replace it. If that was the last loo roll you used, or there's only one spare, put "loo rolls" on the shopping list.
Is the laundry basket overflowing? Sort it out and put a wash on. If you don't know how to sort colours, and if you don't know how to use the washing machine, learn. Is there clean dry washing on the line/in the dryer? Take it, fold it, put it away.
Is the shower/bath grubby? Give it a clean after you've done. Did you leave skidmarks in the pan and a stench? Clean up after yourself, open a window, spray some air freshener.
Are you going on holiday? Make a list of what you'll need, pack your own bag.
Millions more examples. Just notice what needs to be done and DO IT!
Keeping a house tidy and functional requires constant attention and work. Everyone in the house should contribute to this.
