1. We each get to designate one particularly hated chore that is always the other person's job. My job is taking out the bin, his is cleaning the loo. We are allowed to ask the other person to do that job if we think they have not done it.
2. For everything else, if you care that much, do it yourself.
Rule #2 is crucial and avoids the tyranny of one partner imposing their ideas on the other or of dividing up the chores, one partner not doing one of 'their' chores, and the other partner doing it for them because they can't stand it. It also allows for different things being important to us (like if he needs the bathroom to be spotless but I don't care, or if I have to hoover in all the corners but he'd just do the middle of the room). It means he is never allowed to complain that I haven't done something or that I've done it wrong, because if it's that important to him he can put the rubber gloves on and get on with it. It means we sometimes live in squalour when we both feel too busy to do housework but we never have fights about it because the only options are 1. put up with it, or 2. do it. There is no complain or nag option.
I do wonder if this will have to change when we have children, because we'll need to be more organised about making sure everything gets done in a timely way. I'm not sure. I think we might have to be firmer about doing laundry before we run out of clothes or doing dishes before we realise there is nothing to eat off, but maybe the rest can stay as it is
Kitsune put it very well in her followup posts, so I don't have too much to add!
For our #2, our rule was only that
you cannot complain about how someone else did it. You *can* complain if they didn't do it at all. So, for example, if I do the dishes, I don't want my husband complaining that I didn't do ALL the dishes. I loaded the dishwasher, filled the sink, and did as many dishes as (1) filled the drainer and (2) made the dishwater scuzzy.
But Kitsune's point about cleanliness with kids is spot on. I've found that my standards have gone up a bit, and I have two boys now. I get extremely frustrated at the amount of crap that people leave sitting around. And I *hate* working on cooking dinner and then tell people it's ready and THEN have them realize that the entire fucking kitchen table is full of CRAP. We've started docking our child allowance if he leaves things on the floor, and I will occasionally take toys and put them "away" to be donated to charity.
The point someone else made about "having equal free time" is really all I want too. I get tired of picking things up, and doing dishes, and cooking, if my husband is sitting playing on his phone (if he's playing with the kids, fine). I spend so much time cooking and doing dishes on the weekend (because I do a lot of meal prep). The worst is to go in to start cooking, then realize that spouse never did last night's dishes because he was "too tired". So, first I get to put away yesterday's lunch dishes in the drainer. THEN I get to do last night's dinner dishes, THEN I have to fucking start cooking. About 5 minutes in, "Can I help?" How about you just DO IT.
So we have the best harmony when we are working at the same time. It doesn't (and can't) always work that way. So if he's bathing the toddler, I'm usually doing the dishes. We take turns with the breakfast dishes. He's the laundry guy, I'm the cook, and we usually are alternating on the time of day that those happen so we can play with the kids.
The other hard part (and I have no solution), is lack of down time. Due to my younger child's extreme stubbornness, he just fucking won't go to sleep until 9:30 pm, because he naps at daycare (I'm counting the days until preschool). So, I am asleep before he is every night except weekends. So. I don't get any quiet time to just veg out, crochet, talk to my husband. Like, ever. My husband doesn't go to bed until 10:30 or 11:30 pm. So he gets quiet time every night. But he sleeps less. I have many friends who tout the importance of early bedtimes, like 7:30 pm. Every single one of them is a SAHM. Good luck getting your kids to sleep at 7:30 pm if you don't even get home with them until 5:30 pm, and if the spouse doesn't get home until 6:30 pm.
