Speaking as one who used to host (along with spouse of course) the occasional dinner party, brunch, whatever and now doesn't, there are two factors: 1. Kids (older than the "small and cute" stage). 2. Out of practice due to COVID! Worry about the virus is pretty low now, but in the meantime the clutter has grown, social connections have weakened, and the longer you don't have a gathering the less confidence you have to organize one. The kids thing has multiple angles. One is that with all their stuff the house is a lot messier than it used to be, so much more intertia to make it presentable. Another is than active social life exists to fill a need for companionship that is just not as strong when you have multiple humans around you 100% of the time. The third is that the social crowd's growing kids have the same effect on them!
