okay, this whole thing started two years ago.
i had gone through a rough time and something unfortunate had happened which i don’t necessarily like to go into detail about.
my dad, being the way he is, wrote this letter and one of the points he made were about how what happened was “payback” for my mums antics.
i obviously am upset at my dad over this too but i haven’t really got any expectations from him.
but i am close to my mum.
anyways, not only does she show me this letter, but she also drops the whole thing in arguments as a point or a comeback against my dad quite often, which obviously upsets me.
i told her about how it upset me, she did apologise but it didn’t feel sincere, she was joking around while saying shes sorry. “please forgive me your majesty” thats what she said to me while apologising.
and today i mentioned it again, and she said “oh you’re overreacting and being selfish and taking things personally, the note wasn’t even about you it was supposed to upset me so why are you so bothered” so now im wondering if i am really overreacting?
i don’t really think i am? this is something that happened to me and they’re using it as a comeback point in their arguments, i feel like i have every right to be hurt.
especially since my own mother could’ve protected me by maybe not showing me the letter?
let me know what you think please.
