Yes. This!
I worked in a very stressful demanding job three days a week post mat leave. STBXH worked over full time hours but by choice - working on projects he had chosen because he fancied it, saying they would make money/more money in the future. (they never did, I was always the main earner and provided financial stability).
At the end of a week he once said to me ‘why are you so tired, you have had two days off’ and I agreed and said I didn’t know. It was only when I read more about the mental load and emotional labour that I realised why I was so tired. He worked the hours of his choosing then would ‘help’ with other stuff. Meanwhile I held everything together. All the planning, cleaning etc. I was always the one managing my own emotions in the face of him and the kids dysregulating and stripping. he’d do some cooking and washing up and laundry. He’d make tons of mess. Never cleaned unless asked.
When he dropped to two days a week I did the same. I left him to do the mental load and the bulk of domestic stuff. Can’t rely on him to do the emotional labour he is too volatile. I just ‘helped’ with domestic stuff…and oh my god the difference in my stress levels. I finally had headspace to figure out what I wanted to do. What I like. I now volunteer and have taken up a hobby.
I do DIY tasks even if the daily grind still needs doing - which is what he used to do - which is far more stimulating than the constant and endless daily grind activities. Far more satisfying.
I can honestly say that working, helping out with the domestic stuff and doing jobs like mowing the lawn, pressure washing the patio etc is far far more enjoyable and far less stressful. Don’t be fooled by the ‘but he does the DIY’ trope. That is not equivalent to the endless monotony of domestic chores.
Of course he hates doing domestic chores so has taken on more work now so I am forced back into domestic servitude. Hence STBX. Well that and he’s verbally abusive.
But, I can tell you 100 that ‘helping with household chores and child care’ even if you spend the same amount of time working is much less draining and that doing the ‘big jobs’ like DIY and gardening are harder physically but much more rewarding - more to show for it and the impact lasts longer, you get more acknowledgment and it’s less mind numbing and soul destroying with the ‘I’ve just washed up and suddenly there are more pots on the side’ feeling.
