Wow, this is a very hostile way for him to frame this conversation. But if he wants to go there, I suppose you could meet him halfway and take the time. If he plays golf for an entire day every Saturday, you take alternate Saturdays to spend the whole day doing [something outside the house]. Yeah he's probably not going to like having to give up alternate Saturdays. I predict what will happen is he'll say
-he'll take Saturdays and you take Sundays
-oh of course he wants to give you alternate Saturdays but this Saturday he can't because Bob will be there and he only sees Bob once a year. And he also can't give you next Saturday because he has to be at work for a long day on Friday and will need to do his hobby on Saturday to recover and so on. In effect, it will never happen, but he'll always have an excuse.
-you'll take your turn and will come back to an absolute disaster zone at home which will make your Sunday worse than usual because you'll have to clean up all the mess he left
-you going on Sundays won't work because even in your regular schedule you need to prep for the school week on Sunday afternoons, so you'd have to be back early anyway to get that done.
In addition, I've had these conversations where the other person says "The reason can't be the thing you said it is, because of this criterion that I just made up that I declare to be true and you can't argue with it because I said so." This is actually just a way to channel the argument in the direction he wants it to go. It's saying that he knows your feelings and motivations better than you do. It's very condescending and a little bit gaslighting, IMO.
The hobby thing. I don't have hobbies now, except for surfing the internet maybe. And part of the reason is that after looking after the family, I am really too tired to invest any energy in a hobby. My order of priorities is:
1.obligations
2.rest
3.hobby.
I never get to 3 because I never get enough of 2. This is partly because, as a woman, 1 is never done - you are never done with the housework, never done with the laundry etc. Any time you sit down, you remember something else that you should be doing. This leads to two things. A - when you are at rest, it's not perfect rest, it's contaminated rest, because it's really just a pause to catch your breath before you start your next round of obligations. There is never a time I can sit on my couch and say "AAAh, done for the day, now I can relax and take some guilt-free rest time." It's always just "Ok I have 20 min before the kids will be back. I'll call the dentist but I think I'll put the kettle on in case there's time for a cuppa after I make their dentist appointments." B - there is never enough rest time because you are always trying to catch up with the things you're supposed to be doing, that you haven't done yet. So you never get to the point where you are "ready" for 3, because you haven't completed 2 yet. For example, if I sit down with a book now, I just fall asleep. I can't even absorb what's on the page, I'm too tired.
I believe this phenomenon is why men don't want to do housework or why they tend to say "Just give me a list and I'll do it." A list allows them to limit their obligations. When they finish the list, they are done, and they can get that mental "stop" that allows them to feel free. They can stop thinking about it. But you retain ownership of the housework, so you are never done. There's always something more to do.
