@Blutto I'm a little bit confused. Do you all live together or are you keeping 2 houses clean?
are you doing your daughters housework?
why is your wife still working full time when you're 'retired' but actually doing so much for your daughter??
why can't you both be retired & enjoy time together?
id be massively resentful in your wife's position.
as others have said, for some of us the menopause is both mentally & physically absolutely draining.
I want time off to declutter/deep clean etc too, but when it comes to it I'm too exhausted to do it & mostly end up sleeping.
i think you really need to talk to your wife, stop playing hero to your little princess. Or you may well find yourself wondering why your wife has left you.
2 preschoolers 3/4 days a week is just too much, on top of chauffeur, housekeeper at retirement age. You need to decide what you can manage & the princess & knight in nit shining armour need to find some other childcare & house keeping services.
