I love the idea of you both doing a Wordle puzzle while you're on the bus and he's at home. I think that sort of sharing/communication brings a special quality to a relationship.
I also completely agree with the need for alone time. I'd go crazy if my partner and I spent all our days together, especially given our small space. He's of the same mind and spends hours reading in the garden while I write. Fortunately, the Mediterranean climate makes that possible even in winter, but on really cold days he just lights up the outside fireplace.
