I'll share my anecdotal story on the flip side of the coin of keeping house. This past year I closed my business and began working from home working on managing investments and commercial properties that I own. I make a decent living doing this, but it had changed things rather dramatically on the homefront. My wife views it as "retirement" and I now handle most of the kid issues, shopping, cleaning, laundry, cooking etc. Which I don't really mind and normally just take care of things when the market is closed, but it has given me a new perspective on household chores/duties. My wife has several times referred to only one of us "working" and it stings, I do my best to keep on top of things but I can see how being the one at home can make a partner feel like they have to prove their value while the other rarely worries about if they are "contributing" enough.
When I was earning a lot of money over the past almost two decades I don't think I gave much thought to whether I was earning my keep. I do think it's interesting from the biological/evolutionary standpoint, I'm not sure what degree these behaviors are ingrained in our chemistry for men to be more comfortable "providing" versus "maintaining/nurturing" or if it's poorly cultural. It hasn't been even a year yet but I feel like a fish out of water in this role, and to a degree I now feel trapped because I can tell my wife is enjoying not having to do a whole list of things and wouldn't want it to go back the other way.
