ok so this has been eating at me and idk if i was being dramatic so i’m asking here lol

my sister (28f) is getting married this summer and obviously everyone’s super excited. she sent out the invites a couple weeks ago and i (24f) noticed that it was just for me, not me + my boyfriend (26m).

we’ve been together for almost 4 years, we live together, we have a dog together, like... he’s my family. when i asked her why he wasn’t invited she said "well, you're not married yet, it’s just for immediate family and spouses".

it honestly hurt. like, he’s been to every holiday, helped her move, been there when she needed help with random stuff. i felt like she was basically saying he’s not important.

so i told her that if he’s not welcome, i won’t be coming either. now half my family is saying i’m making a huge deal out of nothing and that "it’s her big day".

idk. i didn’t want to hurt her feelings but it also felt so disrespectful. AITA?
