Thanks for all the support and tips. I've been reading them all and this has been an intervention for me.
Spent Sunday putting some little notes on doors and other stuff I forget. Written a morning and evening check list, and updated my home list.
It's been useful to understand how frustrating it must be for DH to do the mental load and follow up after me. We do have a bit of a parent / child thing going on and DH does feel I must not respect him enough to carry on like this and he thinks if I just tried harder I would be able to do this shit. He does need to stop going on about it. We did have a bit of a chat about it and my perspective and although he didn't agree he has just suggested I take some time tonight and relax.
I do have a responsible job (Director level) that I so well and have been promoted this year but I do work really really hard to perform and I know DH does think if I applied the same level of effort/focus I could get home stuff sorted. Work has always been important to me and whatever level I've been at I've given it 100% and this has always been a source of tension but at least now I get a half decent paycheck for my efforts.
In terms of DH being a lazy sod. I would appreciate a bit more help with the 'ongoing maintenance' work but he does do the 'moving stuff forward' stuff like house improvements, in a way I find it easier to do the housework, washing, cooking as I can just turn my brain off and do it whatever kind of fog I'm in and would rather do that than research house insurance or liaise with builders etc which he does, which often happens at the weekend. He also does the school drop off and the kids mainly get the bus getting home 4ish so he does some of the after school too. We do take this in turns as I try to WFH Fridays and in the week if I can. He would say he takes a big load doing that kids stuff most days. We take it on turns on some of the clubs etc. If he had to take the dog out in the morning too the poor dog just wouldn't get enough exercise as I do 20-30 mins and he couldn't fit this in. TBH I think getting more sleep is about the evening and getting to bed earlier as I quite like my time with dog in the mornings especially when I get to see the sun come up and seasons changing as we are super rural.
In terms of why we don't eat together. We do on Fridays and weekend but in the week the kids usually get their own tea with some oversight. We get easy to make meals (ramen/gyoza, pasta and sauce, jacket potato) before I get accused of leaving them with fridge raiders and cheese strings. Then I do adult food when I get in, DH often goes for a run so not home until 8/9 so we do eat late and always have done. I love cooking and do quite a few meals from scratch (not always) but could do more batch cooking. Going to treat myself to a slow cooker so maybe that will change my life!
In terms of whether I've always been like this. Probably yes. I've always been ditzy and forgetful and disorganised and I've always made up for this at work by working like a dog and being cheerful and reasonably intelligent.
I think I am just fucking exhausted which has brought this to a head. Also probably perimenopausal and also waiting for a Hip replacement which also affects my sleep. DH is not great at empathy and I've always known this. This may be neurological too. He does care about me and is an amazing Dad. I know some people will be LTB and when I posted I was angry and fed up and I probably wanted to read some of this to feel justified but in reality I want to make it work. We do always have a laugh when we're not feeling resentment and spending proper time together on a night out and not knackered. I am MUCH better at remembering shit when I'm on holiday for more than a few days and start to focus on family rather than work.
Anyway thanks to all. I don't post on MN that often and it's always useful if a bit hard to read sometimes.
