Except history for each sex is different. Women have essentially freed themselves from domestic servitude - not allowed to work and earn or inherit money, not allowed to vote etc.
The two are not comparable.
Men (white men) have oppressed. And many hold that history in their socialisation still and have an unconscious sense that they don’t need to hold onto the day to day, mundane, daily grind tasks and emotional labour that keep home and family life going. The work that has been necessary for all to thrive, but undervalued for centuries because it’s ’women’s work’.
It is a pattern born out of the patriarchy that is hard to shift.
my StBXH and I had a period where I could no longer carry it all and I handed over the mental load to him. Several failures that resulted in upset children made him realise that he needed to apply his brain to this ‘grunt work’ and - despite his man-brain, he could.
Within two weeks he was complaining he was exhausted. He was doing paid work two days a week btw. Whereas when I was doing the same (but doing paid work for longer hours), he couldn’t understand why I was exhausted. And we had two hours of a cleaner a fortnight when he was doing it.
He didn’t connect the two. It is different when it’s him carrying that load to when I do.
I held off picking up the mental load again for a while so I could build myself back up, and I lived like him for a while. I did half the cooking and washing up and half the laundry. Half the school runs and watching the DC. I offered to help with domestic chores when I was free and asked him what needed doing. If I noticed a job that needed doing like shelves needed putting together I’d just take myself off and do it. I worked in paid employment and on those days that’s all I did.
And reporting from the other side…
IT. WAS. SO. MUCH. EASIER!
I felt relaxed. Because I had low mental load. Unfortunately I still had to carry the emotional labour because he continued to dysregulate like a massive toddler. He then had an injury and I had to pick it back up again and could never even it out. Bottom line is he didn’t like holding it all. Very few of us do. And historically men have delegated it to women because they have had the power.
