ADHD

When I lived with a partner I we would usually make some bigger meals on the weekend and I would do most of the work, but she would help here and there to make it a bit interactive and thus more "interesting" from an ADHD perspective. That would be good for various meals through the week. Doing it together made it easier for me. She would then help to fill in the gaps. Still more burden on her than me for that particular task. But we balanced that out with other tasks.

When you have a partner who doesn't mind doing the some of the stuff you can't get your brain to allow you to do and then you do the things they aren't good at or don't like to do, it helps. IMHO you don't have to split each task evenly to make it fair as long you do different tasks that require a relatively equal amount of effort for the person doing it. Also, taking into consideration specialty tasks that would otherwise require hiring someone. Like I was able to do electrical work, computer repair, and some home repairs that she wouldn't even be able to touch, for example. Those took a lot of time and effort and saved either time and effort or money. That should be considered when thinking about equitably splitting chores.

We also didn't have the problem of gender role based task discrimination. Not sure if that's something you need to deal with, but neither of us were men and both didn't really prescribe to a gender role basis for types of chores, so there weren't really those tasks that one of us felt should be done by the other gender and thus not counted as chores to be split. Everything was on the table for equitable splitting.

Now that I live alone, it's a little more difficult, and I'm not good at cooking for myself, but at least it only affects me, not my current partner. So getting stuff for quick sandwiches for days I don't have the spoons is fine, but you can't expect a partner to make those sacrifices.
