I agree with what you have said, that it is the little things, the details and consistencies, that add sweetness and caring and security to life. And there is validity to the idea that a stay-at-home parent is a professional, and as such can fully engage in that profession with a determination to perform to the best of his or her abilities.
I think you have missed something, though. I believe that your wife and most wives and mothers (regardless of how successful we might seem in the tasks of mothering or housekeeping), don't approach that role solely as a job to be done, but as an expression of our hearts, and because of that our success can't be measured only in task completion.
It is abusive when one mate puts themselves as the arbiter of how successful the other is at fulfilling the their role; as though performance review were the equivalent of distribution of work negotiation,and as if that were there right. That wife or stay-at-home dad isn't self-employed, but neither is he/she an employee. What they have is a partnership. If one individual takes only the managerial role, and sacrifices the partnership aspect, he might as well be loading a pick-up truck full of rocks ready to take aim. And if he withholds the benefits of partnership until such time as the other measures up or reaches that marker of success, then it's too late, the rocks have been cast and the damage done.
Look in your wife's eyes (not just you, but any husband). Aren't there some broken windows there which might have a much more devastating effect than the external functional ones you seem to be so fixated on? If you neglect those windows you will find even greater feelings of abandonment exist in your household than any that could be produced by unfolded laundry or improperly loaded dishwashers. And you will definitely run the risk of invaders if this continues-in the form of other interests or people which further detach your wife from you.
Kelly appears to be a very loving and engaged mother. Wouldn't it be wonderful if she were an equally loving and engaged wife.
You say that children are at risk if their physical environment is chaotic. OK. But children absorb their emotional environment. What a child sees in their parent's relationship, with that osmosis unique to children, has far reaching consequences for good or for bad.
YOU might try reading that wonderful little poem "Children Learn What They Live"
The first line is "If children live with criticism, they learn to condemn." Do you want your children growing up to condemn their mother?
