Bit of background - married for 13 years, currently going through divorce. Ex frequently uses foul language when texting (we don’t see each other / speak on phone) e.g. F off, dckhead, kob, a couple of times c*t, things like “you’re a terrible person” “you’re an awful human being”, “get off your lazy ase” Etc etc. You get the gist. I never swear at him and try to remain polite.
AIBU - Divorce is a tense time where emotions are high, inevitably people will get upset and say horrible things.
YANBU - There is no excuse for this type of language. Ever.
I feel that as it’s been going on for so long, I’ve lost sight of what is normal and what is not.
