Many thanks for all these useful ideas.
Over the years I have always dealt with the laundry, though I do not iron his shirts. I am happy to continue with this.
When I worked I had a cleaner in term time.
He has always done the garden. I do not have green fingers nor any real interest, but occasionally I will help with some clearing up jobs. But he has done no gardening since October.
He is real good at some DIY jobs, so no way am I going to learn new skills in that direction, that would really upset the apple cart, as he can do small electrical jobs, mend most things, sort out computer issues.
He prepares his own breakfast and lunch every day. He makes my lunch on Saturday and will cook once or twice a month in the evening. He is not helpless.
I suppose it us all the little things he does not see need doing that niggle. Replacing the toilet roll, that sort of thing,
Cleaning is the biggest job and I have reduced how much I do considerably. He is a collector, so every inch of the house is full, every surface covered. I once counted up how many items I had to move and dust to dust the living room: probably over 100. So that is done very infrequently. He doesn't see the dust or see the need to dust, but eventually it gets to me.
He makes lots of mess in the bathroom, and drops biscuit crumbs in the sitting room, these are the annoying things as if I say anything he thinks I am making a fuss over nothing.
One thing he has pretty much taken over is the shopping. He goes out every day for his paper and picks up whatever we need, including fresh produce from the greengrocer, butcher and baker . About every two months he goes to the cash & carry and buys in bulk ( creating storage problems). We live very near Aldi so either of us will pop in there any time, and about once every six weeks I go to Morrisons to stock up on things I can't get locally. So we do share this task.
DH is not in the best of health, so I bear this in mind. We have both lost strength and have some joints affected by arthritis especially hands and wrists for me, but the back for him.
I am sure we can work something out.
