Don't get me wrong but for me opposite is true. Even though S.O. helps with chores you have to book everything for 2 people, adjust plans accordingly. Basically consumes your processing power with many more variables to account for. OTOH when I was single, I was able to focus on something whenever I want and wherever I want. This is especially true for less hours but more fragmented structure. For instance, I would carry my laptop with me everywhere since I don't have to carry other things. And when I am sipping my coffee I get an idea and implement/test on point. Meanwhile with someone it is not so easy. They see you having a backpack and then they add stuff in it since you're already carrying it. Not complaining here, since it is also logical thing to do. Then, you need to keep your attention on your partner. You cannot immediately focus on something of your hobbies or work. tl:dr; Basically with someone, you need to create slots like "work" "hobbies" "events" and "private". Sometimes you will want to get things done in another slot but having to communicate and reschedule everything is too much work. So you try to be 50-70% productive on that slot than whenever (now?) you want.
