I want to know if I can move in with my aunt now because I've been wanting to move out for years and she told me when I was 14 that I could move in with her . I have problems with my dad and I can't stand to even look at him because he is &' was abusive to me and my mom and brothers . If I move out can they force me to go back home ? (I'm also done with high school)

Not unless your father agrees... at 18 you won't need permission.
