I would refuse. Since when has he been an expert on Child Care, Household Management, Nutrition, Cooking, Shopping, Cleaning, Gardening, and all the rest? No. Has he ever, effectively and properly, taken over the role you perform for at least a month without a break? No. Does he know anything about it? No. Tell him he has no right to do this. Do you micromanage his job? Why not? Same reason he can't micromanage yours.
You shouldn't be driven back to work to escape a monstrous husband.
He is being totally unreasonable and I am sure he's lying about his Colleagues doing this. Maybe one of them does. But all of them? Huh! Their wives would leave, surely?
What he is doing, and planning to do, constitutes coercive control which is an offence under law.
He is: -Closely monitoring your activity. - Monitoring your time.
-Repeatedly putting you down, such as saying you’re worthless. - Humiliating, degrading or dehumanising you. -Denying your freedom. -Constantly criticising you. - Forcing you to live by his rules - Taking control over aspects of your everyday life. - Policing your lifestyle.
I'd say that his "everybody at the office does it for their wife" is gaslighting.
Plus he is completely unaware of the important work you do 24 hours a day caring for your 3 year old. This alone is exhausting.
Planning, shopping for, cooking meals and clearing up or a family of five is a full-time job.
I know somebody with one child, married to a Lawyer, who is a SAHM apart from a small time when she did a very PT job. She has a Cleaner once a week. Her DH does not make these demands. In fact on Saturdays he gives her a day off and looks after their child while she does anything she likes, usually visiting museums I think!
Take a step back. Would that younger you, when she was an efficient and capable lawyer, have let one of the other lawyers set her a list of household tasks, ignoring the vital demands of child care which are unpredictable. Then would she spend the day anxiously trying to achieve his goals [which he has never done], always aware that at the end of the day she would allow him to go round the house - her home - to critique her competence at accomplishing his list of jobs?
Would you have agreed to anything like this when you first met him? Or -
Where would you have told him to put his list?
