Someone please help me...😭idk what to do...😣😣

I know this has nothing to do with the topic but idk what to do. My parents are forcing me to move in with one of them after I graduate high school in 2 months in already 18 and want to move in with my boyfriend. I can't stand my mom she's always manipulating me and controlling me. My whole life both my parents have been strict and even at 18 I can't hangout with friends when it gets dark I can't take it anymore they still treat me like I'm a kid. I'm in NJ so when I graduate is it possible for me to just tell them no and move in with my boyfriend and him family without my mom having to call the cops because she said if I tried or ignored her and told her I'm not coming home she would call the cops on me to come get me. Can she do that?....
