I am much too old for this but for years I have been friendly with a woman (since school) who always delivers veiled insults. For example she'll say things like "oh xxx said i looked much younger than you" etc. It's always in a jokey manner, so it seems a bit off to call her out and I generally brush it under the carpet. I hadn't seen her since lockdown and she did the same thing again and something inside me snapped. I don't know why but it seemed to take me 30 years to realise she knows when she is insulting people and does it on purpose. Would it be unreasonable to just stop seeing her? I have called her out on previous occaisons for being rude but she never seems to learn and I ended up very upset.
