Exactly why my parents stopped hosting dinner and cocktail parties. Nobody ever reciprocated, it was a lot of work, and eventually they just stopped.
We were hoping the other families would reciprocate, and maybe invite us to some of their gatherings (especially two families who hang out together quite a bit.) So far it hasn't happened at all, they just receive our graciousness and move on immediately.
Or think they’re doing you a favor by not rejecting your invite
Perhaps some people can sense this stuff subconsciously. Relationships should build naturally.
Low key this feels why so much of our social life gets productized/monetized.
