Are you of menopause or post menopause age, because this is probably some of the cause of your unhappiness, because you have become less tolerant ?
You feel that you are unappreciated ?
Secondly, you do not sound like you operate as a "team" at home.
You have not mentioned who does these things ?
Or do you do all the below as well ?
House maintenance & DIY, insurance
Garden maintenance
Car/vehicle maintenance, MOT, insurance, tax, service, clean, breakdown
Holiday booking
Birthday, Christmas arrangements, date nights ?
Do you both have equal time free for hobbies ?
I would suggest
Buy a robot hoover
Get food shopping delivered or click & collect
Do not cut your hours, because this will affect your pension & savings, protect yourself.
Why can't he cook pizza or something simple once a week for you both & wash up. Or get a takeaway ?
If you were sick or worse, hoe would live ?
Plenty of people live on their own
