I just stopped doing it all. I started by stopping doing any of DH's laundry. I then stopped running myself ragged every time his family came to stay and left that to him. I'm afraid our carpets haven't been steam cleaned for fifteen years because I felt so furious lugging a vast rug doctor up and down stairs, dripping with sweat while his 6'1" carcass watched footie.
To be fair to DH when I explain, he listens. So I pointed out he is not 'helping' me when he does stuff with DC or around the house - he is doing part of what the two adults need to do. Once he asked if I wanted to go and see a film that night and I said yeah, so he asked me to 'just book some tickets and get a sitter.' I said, 'Nope. You asked me on a date - you sort them.' It was a real eye opener to him, ringing around five or six potential sitters to find one that was free, and online booking the cinema. That 'coudja just' took him the best part of an hour. I explained this is normal and it is what many women get pissed off about and call 'wife work' or 'life admin' as every job in itself is really insignificant but they eat into free time. DS2 is autistic and had a lot of issues in his teens with loneliness, social anxiety, a bit of bullying, very low self esteem and low mood. I spent hours supporting him and pointed out to DH this is work, it's the 'mental load'. Tbf, he was brilliant about it and if I was supporting DS, he'd make dinner, wash up etc.
I also stopped being very inventive with cooking. Same old easy family recipes. he got bored and now he does the bulk of the cooking too.
You have to down tools, explain the workload in an entirely non-accusatory way, and lower some standards.
I now do half the work and DH does half. I know he thinks he does WAY more than his share and he also prides himself on being a man of exceptional wonderfulness just because he does what I do without expecting any standing ovations.
