Ideally, do just what you said and have another person to do those things. My wife has ADHD and I take care of all financial stuff and most of the cleaning (we also have a maid but she only comes weekly). We each cook for ourselves, but she largely does pre-made meals and takeout, whereas I actually cook all of my food from scratch.

That maybe sounds asymmetric and unfair, but though I'm healthy now, I've been in situations in the past where I couldn't even dress myself and she took care of me. It's a lifetime partnership. Workload doesn't need to be perfectly symmetric at all times. Besides, when I lived alone before getting married, I also paid all the bills and did all the cooking and cleaning myself, so it's not like this added work.
