AITAH for "choosing" my bf "over" my sister?
So. My sister (18F) and I (17M) have always had beef. She was always the "bad kid"; she threw parties, got her ass sent to military school, stuff like that. My boyfriend (17M) has been here to help me with everything since we were 15. I love him more than anything, if I'm being honest.
My sister has been a recurring problem on this account (which is only for my AITA stuff). She has a problem with flirting with my partners, stuff like that. She peeped in on my bf pissing one time.
Anyway, now to the problem at hand :,)
My sister has FINALLY graduated from the military school (they have a really early graduation, ig. that weirded me out too) and she's trying to come back home to live with our parents. I would rather spontaneously combust than live with her again. My bf's parents like me, and would be 100% open to me living with them and my boyfriend (I practically live there anyway).
My sister walked in on me packing my essentials a few hours before going to talk to my parents. She asked me what was going on, I told her (I don't sugarcoat anything </3). before I could say anything else, she ran downstairs and told my parents.
So, now we're here. My family is telling me that I'm a monster, my boyfriend anf his family are telling me that I'm in the right. I am currently sitting on my boyfriend's bed; I have not unpacked my suitcase because I feel like I should go back, and i haven't slept all night.
Update: I unpacked :)
