oh bless you both!
My lovely ex in laws are one of the most happily married couples I know but when ex fil retired (against his wishes really he worked a manual job and he became unable to keep up really) but he had worked long shifts most of his working life and ex mil had like you run the show at home on her own terms for over 20 years.
This happened when I was newly wed to ex and I (and the dd and other dil's) got several calls from my normally very even tempered, laid back and adaptable mil starting "I am honestly going to kill him!"
He was similarly going "stir crazy" and calling the "boys" giving it "I'm going off my nut with boredom!"
Well, he had a birthday during this time period so all we "kids" and their partners/spouses clubbed together and got him a shed and kitted it out with a workbench etc. Is something like this an option for the pair of you?
This did seem to alleviate the tension somewhat.
Difficult during covid times but also they each at our suggestions joined various clubs and hobby groups outside the house to get a break from each other. (This came about after a particularly trying day for them both when her solution was 3 trips to Tesco in one day! )
They're both fine now, but it was an...interesting...point in their relationship.
Mind you my 18 year old daughter is the same. I wince and inwardly scream when I see her putting stuff on the airer, it's all over the place and scrunched up.
Ha! I've been flamed for this on here but my dd from around 12/13 did her own laundry!
Came about due to an argument over me apparently not washing the Exactly right school polo top (all out the same pack/set but apparently a particular one of these was a favourite as somehow softer? I didn't notice the difference myself clearly) so I showed her how to separate and launder and how to use the machine and said she could very well do her own! She actually really liked it! Found it a meditative job that calmed her after a stressful day (yes she's weird!) and meant she could wash not only uniform as she wished but the clothes she wanted to wear of a weekend (this being the age this sort of thing became important to her) it also taught her indirectly the benefits of checking care labels BEFORE buying an item of clothing and therefore not landing herself with something that needed hand washing or dry cleaning as she learned to appreciate what a faff that can be. I also got her an airer for her own room (she had a decent sized room so she could hang it as she wished - which also taught her that just flinging it on any old how when she could finally be bothered wasn't ideal!  mainly as it resulted in clothes needing ironing whereas I shake and hang my stuff flat as poss and avoid ironing wherever possible.
At 18 yours is certainly old enough to manage her own laundry inc the hanging/drying of it and can leave yours well enough alone?
My own dd had on occasion before this also tried to be "helpful" and wash things of mine and either shrunk them or colour run them!
Much easier to do our own!
An awful lot of these are examples of "strategic incompetence" though aren't they? And "mansplaining" too
I wouldn't and didn't put up with that. Ex tried it on early in marriage I just laughed and went "nice try now do it properly"  or if it was something of little matter to me left it done half arsed! Mainly things that affected him so if he eg didn't wash his sports kit or forgot to put his lunch in the fridge once made it was his lookout if he had an upset stomach or had to buy lunch or his kit wasn't ready when he wanted it and smelt rank! He soon learned not to disadvantage himself
I will say he always did an excellent job of shoe shining, cleaning down worktops, polishing and dusting and cleaning the windows - but he was army raised and worked so I suspect a lot came from that.
Having recently watched Downton abbey again I think it's clear the reason the marriages of the upper class tend to have more longevity is far more to do with the ability to avoid each other easily in a large house rather than class per se! 
dd used to wander around with a strappy vest top, shorts and flip flops on in the depths of winter and whack the heating on all day! Now I can have it on just when I want as I have the sense to dress appropriately for the season!
All of this perfectly illustrates why I'm much better living alone!
@Mammma91 that's beyond the lighthearted tone of much of the thread imo that's appalling behaviour on his behalf
