Actually the average man's brain IS biologically different from the average woman's but I can see that wouldn't suit the mind set of many women on here.
OP my DH is very disorganised and untidy. We've been married a long time but looking back previous boyfriends were nothing like as bad in that respect as he is. The previous two were actually good at all that practical stuff and one would pull me up sometimes for not sticking to his standards. (I'm not the tidiest person in the world either)
No, I didn't think about the repercussions of marrying someone like that - shock horror, I could not predict the exact way the future might evolve. We were late 20s when we met. We got on very well, never had any disputes etc. When I first saw his bedroom I was amused by the mess. I realised I had been frantically tidying my place everytime he came round and that he wouldn't have noticed. I saw my former bfs as over fussy and didn't see it as something attractive about them, although it had its uses.
I think things weren't bad at first in that respect. We had a house that was too big for the two of us (3 bedrooms in anticipation of a family) so plenty of space to store things. He was at work for long days and I got home earlier so did the cooking. At weekends we went out and had fun. It was 9 years before we had our first child and a few years after that he started to work from home. He has always been good at booking holidays (I've only booked one that I can recall) and did projects round the house like putting in built in wardrobes etc. He also took responsibility for the cars.
Fast forward a number of years. We had two kids and a cluttered house that had by then had a loft extension where he worked. Issues with one of the kids schools due to their needs. We moved to a bigger house that had several empty rooms at first but is now full. I regularly take stuff to the dump but it is still cluttered. The kids are teens and messy too. I work longer hours and more days so housework isn't my priority when I get home. DH does try, no doubt about that. Better since the first lockdown. He now shops and cooks regularly, makes more effort to tidy and do the garden, puts washing on (but never a full load unless I direct him??). For years he took the kids to school, and attended school meetings, appointments etc because he works for himself and can be flexible.
I still get irritated that washing up is left near the dishwasher, not put in it, that rubbish isn't put in bins (we have a bin in every room!), that the kids copy his sloppy habits, that all surfaces become cluttered and things that fall on the floor stay there.
But after 30 years I've probably got as far as I can with improving his domestic skills. And although it's a biggie for me, I have to admit he does pull his weight in many other ways - eg he is the main one to ferry the kids around which gives me chances to have time alone at home (blissful as it is so rare).
So I think compromise is in order unless there are other things about him that bother you. I really don't get posters who advocate leaving a long term relationship over one thing - do they really find someone perfect or just ditch the latest guy every few years?
It has never once crossed my mind to leave DH because of his disorganised approach to much life, but admit it has made me CROSS!
