AITA for not staying with my family?

long story short i (17f) have never liked being around my family. my mom and i argue constantly & she kicked me out about two weeks ago, told me she was going to change the locks and all (which tbh was a RELIEF). now she’s begging me back saying how sorry she is and blah blah blah. my grandparents live right next door & they have custody of me since i was 8. they’re all very toxic & we’ve never had good relationships and recently everyone jumped on my back about how im never home.

i’ve been living with my bf (17m) and his family for over a year and will occasionally go stay a few days with mine, but never more than 4 days as i genuinely can NOT handle being around them for any longer (sometimes not even that long).

i ended up having a talk with them and telling them straight up that i am growing up and making my own decisions & that i don’t like being around them bc everything always has to be an argument and the only way they think they can get their point across is by screaming. there has been plenty of physical fights as well,, why would anyone want to be around this?? in the end they denied everything which only made me angrier but it’s what they’ve always done. my bf’s family is the absolute polar opposite and since my first time being here i never wanted to go back to my family.

after our talk, they were obviously mad but said that if i didn’t want to live with them i didn’t have to (all on recording). it’s been about 4 days since our talk and now they’re blowing my phone up telling me it’s time for me to come stay a few days. i’m immediately pissed off because that’s what i’ve been doing for the last year and clearly it wasn’t doing me any good, so why the hell would i want to start doing that again? not to mention i dont even have a room there. i’ve tried to let them down gently every time but im about to explode. it’s getting to the point where i cant stand to even see a text from them. i had planned to go visit for a few hours tomorrow but now i don’t even want to do that. am i just being an asshole or am i justified?
