This might be a long reply - sorry!
IN THEORY, we have always shared the tasks. DH is very willing. BUT he has always had to be told of almost everything that needs doing (including in the garden, with cars, with anything DIY-style) and is painfully slow. His mother warned me of that before we married. I thought she was joking! He even has to be told to move or put away things he has been using and now finished with.
In my 30s, with two tiny children, I was diagnosed with scoliosis which initially meant I was in permanent agony. I designated several more difficult "physical" tasks to him, such as vacuuming and window cleaning. 40 years on and I would estimate he has vacuumed the main carpets no more than twice a year, and spare bedroom etc never. He does not know that rooms have edges, skirting boards or cobwebs on ceilings. I struggled myself to do them, but once the kids left home we have confined ourselves to the hall and one downstairs room and we ignore the others unless we have visitors. Then, of course, it is a mammoth task and nearly kills me.
I "only" worked part time when the girls were young and did almost all housework and the garden, washed the car etc. I became pretty handy with a saw and a drill too.
I once let him loose with the household finances (mainly to make sure he could manage without me) and we were overdrawn within the month. He has no idea how much we have, but fortunately isn't much of a spender.
He doesn't even see that the lawns need mowing unless I tell him. When I worked full time (and it was 60 hours a week during term-time and not much less out of term) almost all cleaning/maintenance was ignored apart from essential stuff
Needless to say, the garden is often overgrown, the house is untidy, only the main rooms are clean (but in a mess), and it depresses me.
Once we retired, rather than any re-think of the workload, I simply took over almost everything I could manage apart from mowing the lawns and loading/unloading the dishwasher.
I would gladly move to a much smaller house but DH won't hear of it. He simply doesn't notice what a mess everything is - and I really mean a mess - but I can't manage a 10-room house with 3 bathrooms, utility etc myself. Oh, he used to cook at times but since the children left (25 yrs ago) has only every done ready-prepared food.
I do despair, but what can I do?
Sorry for all that cos I imagine the OP meant it to be light-hearted. Perhaps the fact that I've spent all of this year having cancer treatment and still had almost no help from him has made it all seem worse.
