How can I sort/deal with this issue

I don’t really understand what the problem is. If there’s anything you particularly want from the shops then let him know the night before, or do a big shop yourself to cover the week.
Unless you only have one set of clothes it doesn’t matter if you miss the 1830 washing slot surely?

There are plenty of people who like routine, and your husband is one of them.
I hope you both find time to have some fun, along with all the domestic stuff.

I would just write a shopping list the evening before and leave on the kitchen table.. and I would load any washing I need doing into the machine the evening before. Then I would have my own, much looser routine and get up when I wanted to and leisurely have breakfast whilst he is out and just enjoy my own company.. I think he probably feels safer with a strict routine but you can surely adapt to him..

Shopping every morning!! Why ??
He obviously needs his routine but I understand why it drives you mad. May be OCD or perhaps on the autistic spectrum - many people are undiagnosed and lead happy successful lives. Whatever the reason it seems you have no option but to try not to to let it irritate you (easier said than done I recognize that ) My DH has been diagnosed with Alzheimer's Disease, he has always been a creature of habit but it is now on a very different level. His latest thing is going out for coffee/ cake every morning!!!! Never wants to miss , he lives in the moment and has no concept of how often we go. I just smile and agree to go with him - not easy! Gooduck.

I think perhaps inside he is frightened of a life without structure or purpose or being useful post retirement so he has to go out everyday and only get a few things so tomorrow will bring more need/structure purpose. Just "being" isn't enough. He sounds short of hobbies or other ways to enjoy his time.

It is really hard for you, but he may experience suggestions for change as a threat and be unaware/unable to see emotional consequences for you.

In an ideal world he'd be able to discuss it openly without him feeling threatened or go to a counsellor to work out compromises if you cant stand it anymore.

Definitely stand up to him if you want to pop into the supermarket in an afternoon. Are there things you enjoy doing together, if not then it's what can you do to make your own life more satisfactory with others/other activities. all the best, its a tough one.

Sounds normal enough to me someone he is someone who has always liked to follow a path you chose him, you said he’s always been structured so what’s wrong
I m always up by 6 at very latest 7 and would feel quite slack to lie in till 9 I would be the one up and trotting to the shop by 9 am if you’re an early bird it’s very hard to tap your feet till much later
Nothing wrong with routine if that suits the person My dad always had meals at the same time always got up at the same time went to bed at the same time but he’d been in the military through the war years and everything ran like clockwork and he never got out of the habit Mum was a freer spirit but got more like Dad as years went by.
Instead of being irritated by him why not accept him, you chose him a long time ago, at least he’s trying a lot of men do nothing

Without knowing anything about his working life, it’s hard to say. Maybe he worked to a strict timetable for 40 years and it’s ingrained in him. Some people do have to measure out their time in hourly slots, teachers for example, or even smaller measures e.g. people who had to fill in time sheets to charge clients for work done.

Post retirement, some people feel they still need structure in their life else they drift and do nothing.

If he is so very rigid then it might suggest he is on the ASD spectrum, needs routine, has a clear demarcation between what he is and isn’t comfortable with and sometimes needs instruction i.e. happy to go to the shop but needs to be told what to buy.

Surely the easiest solution would be to sit down together and write out a daily/weekly shopping list.

I don’t blame him for wanting to shop at certain times. I avoid my local store from 8:00am to 8:45am (full of schoolkids buying tuck). Same at lunchtime and at the end of the school day. That mid-morning slot sounds about right.

Do you think men miss the routine of work once they retire?

It’s the other way round for us. I’m the early riser and I do the big shops with menus in mind and he does the small top-up shops. Works for us.

Different people have different expectations from relationships. Many people would be ok with this others like you not so much. What in this do you think you can change? I’m assuming he has good points too,do they outweigh the negatives? Is it possible he was always like this but when working it wasn’t as obvious?

Sounds like hard work to me just do one big shop once a week then your husband can go out and pick up any extras as required.
As for the washing which actually is a total mystery to my husband why do it at 6.30pm I tend to do different loads on different days first thing so I can hang them out.

Why don’t you go out and do a big shop?

Why not work out the night before what you want him to buy?That said, it’s not as if 9.30 is sparrow fart though!
(Many on the Good Morning thread seem to have shopped and back again by 8!!!)
Do you have to run the washing machine every day, and if so why can’t yesterdays clothes go in and put todays into the washing basket when you go to bed?
Yes he is inflexible , possibly OCD but you need to work out your own stratagems to go with the flow- not try to turn the tide!
