When people react with very significant emotional dysregulation for reasons like “you weren’t there for our scheduled catch up”, then actually I’d assume that was a them issue, possibly linked with something like low self esteem or a significant fear of abandonment.
I agree tbh. Im kind of iffy on whether that person was in the wrong Im ngl. For me my first thought was that if you make a commitment with someone you should either honor it or tell them you cant do it instead of just ghosting. Every once in a while is nbd (especially if it isnt anything serious) but I think all the time would send the message that you're flaky/unreliable.
For me, someone being like that isnt an issue, but for others it might be bothersome and I can see why if the expectation is being set and then not fulfilled
But either way, whenever people fling "omg you didnt [msg me back, ignored me, left me on read, yada yada]" at me, I immediately disengage even
further lol. I once had a friend (an ex friend, obviously) who sent me like 6 paragraphs in a private message about how he went thru our DMs and counted the number of times he said "hi" first, and it was more than the number of times I said it, so this was evidence that I wasnt "invested in the friendship" and that he felt "like a clingy girlfriend" so for his mental health he had to block me.
This sounds like an exaggeration but this was literally verbatim what he said to me. I was like ok, bye!
These days having dealt with a lot of ppl who have personality disorders, attachment disorders, trauma, emotional dysreg etc I do my best to try and let people know what is going on and where they stand (mostly by being as up front as I can that I am not a reliable socializer, if I leave mid-conversation, if I cant do a scheduled activity etc) but this is something I view as a courtesy/an extra step, something I'm doing for their benefit that is above and beyond what they should actually realistically expect from me
(meaning that if I neglect to do it a few times I shouldnt be pummeled with someones hysteria/outrage over it). Since even
if a person isnt very reliable socially, they're not really doing anything morally wrong (other than I guess wasting people's time? But I mean, all I was doing was watching The Devil's Plan and playin Medieval Dynasty so its not like my time is particularly valuable as the CEO of Nothin Doin over here LMFAO)
