All depressingly familiar. DH has got better but still very unequal.
We lived together as students (from third year) and got married literally in college, so neither of us has ever lived alone. That means I've never paid a utility bill, arranged home insurance, submitted a meter reading, mowed the lawn, configured a router, cut the hedge, changed the oil, etc, and he's never cleaned a bathroom, ironed a basket of washing, arranged a child's birthday party, called a plumber, cooked Christmas dinner, etc.
I wouldn't like to have to take on even a share of the financial management as I have a serious blind spot when it comes to money matters. I have no idea how often a gas bill needs paying or whether it's £50 or £500.
DH organised our holiday completely solo last year. The parts I usually do were horrendous: imagine a four-hour cross-country railway journey without booking seats. Thank fuck I packed ... This year I was happy for him to make all the location/accommodation decisions but referred back to last year's experience regarding logistics.
I remember my best friend's mother saying she'd cook anything for dinner so long as someone else chose it. At the time we laughed and eye rolled; now we each have a husband and three sons and we get it. The decision making is the worst part of it.
