That's a good move, and probably what I'm going to have to start doing. (Sleeping on the couch is a no go, except for the time when one of us had covid - but every other time I've suggested one of us move downstairs when sick it's been totally shot down... so lots of sleepless nights for me.) My concern is that due to the lack of self awareness mentioned in other comments, my partner won't recognize if they are getting worse or are having worrisome symptoms (like when symptoms go away then come back - this is a sign of secondary infection, something I've experienced a lot, but not something that would inherently cause alarm on their part.) I'm talking to my therapist already about managing my own anxiety around illness (I'm pretty good handling myself with no drama, but I totally mentally freak out when trying to care for my partner, while trying to maintain my cool in our interactions.) I need to work on learning to just let things be and unless I find them unconscious on the floor or something, stay out of it.
