Any advice for cutting contact with my dad as a teen?
So, a little background, I'm a queer + trans/gender non-conforming teenager (17) who's parents are divorced but have shared custody. I hate my dad and want to cut contact as soon as I turn 18, but I have no clue how to go about it. (for more context though it shouldn't neccesarily be needed: my dad is a narcissistic asshole who I've hated practically since I had a concious, and he's been bordeline emotionally abusive to me, my mother and my sister since I can remember)
i plan to decide to live only with my mom as soon as i turn 18 (because thats when i can legally decide that) but because my sister is a lot younger than me, i still feel responsible for protecting her. i dont think my dad would EVER be physically abusive, so i dont worry about that, but when my parents seperated and my dad moved away, a lot of the borderline abuse that my mom had been taking fell to me, and i dont want the same for her.
the only things i would worry about would be my sister and my things at my fathers house, so any advice regarding that would also be appreciated. my mom knows of the situation and i think shes aware that i want to cut contact so thats also not an issue. I do worry about things like my sister graduating middle school and subsuquently high school, and things like dance recitals, etc.
i'm planning on going to college out of state so that it will be harder for him to visit, maybe even across the country. i do live in the US, but not in any midwestern or southern states, and im not planning to go to college in any of those places, so laws and trans/queer harmful laws arent really an issue for me.
basically i would just like any advice on cutting contact in general, and how to navigate younger siblings and just going about navigating a situation like this. thank you guys in advance, i know this is a really heavy topic <3
