To an extent this is my marriage. My wife and I both own our own companies. Mine is much more established and therefore offers me some leeway on my in office time (I'm an accountant). This means I often spend more time taking care of our children. I also cook, make grocery store trips, clean (to an extent), etc. She still helps around the house which isn't ad much as it used to be. But I see her working her ass off so I don't complain.
As for protecting me....no. I'm a pretty large dude. 6'3" 250. So unfortunately when things go bump in the night ya boi gets to go investigate.
My now wife hid them from me for about 3 or 4 months. She's more flatulent than me. Always to think about how hush hush it has to be before everything comes out. I farted in front of her within days of our first kiss.
