My Dh was brought up in a very dirty messy house and so hes never really had a routine and doesnt see mess. So if I wasnt around he probably wouldnt wash his towels or bedding for months because it just wouldn't occur to him etc
I found a few things that help:
He does the vast majority of the cooking, washing up and food shopping. Hes terrible at putting the washing up away, he tends to get half way through and get distracted etc, but all in all it means meal planning cooking etc is never something i have to think about and i just do a bit of extra washing up and kitchen cleaning.
He washes his work clothes, i wash everything else, but if I strip the beds he remakes them (its a massive help because I have a bad shoulder) and he cant miss an unmade bed
I do the rest of the cleaning and tidying, but he tends to hoover sometimes if my shoulders playing up although hes terrible at it, ive seen him hoover round a book on the floor because he doesnt really register it as anything other than an obstacle.
So between us its fairly evenly divided but plays to our strengths (he hates being hungry where as i tend to miss meals if im not paying attention, so hes a better cook, and my attention to detail is better for tidying)
Ive also learnt to adjust my standards. The worktops get cleaned at mealtimes, if he messes them up inbetween and doesnt think to clear it up i just dont worry about it, no ones going to die because there are breadcrumbs on the worktop for a couple of hours
Also having a place for things is helpful. He would leave paperwork all over the house because thats what his parents did. All paperwork now goes into a box file for the year, so it doesnt end up piled up everywhere. There is a key and loose change bowl so he doesnt lose his keys (and neither do i) etc etc
But he is messier and sometimes it does drive me mad tidying up after him every day. But then i go to his parents and see their sofa surrounded by used tissues and chocolate bar wrappers and unopened mail and realise just how much he does try compared to how he was brought up
