I need help fast please :(?

I'm 17 years old and i'm wondering if there's any way I can move out of my house. I live in Florida and I turned 17 two months ago. Please no rude comments I'm just trying to find answers. I have a 19 year old boyfriend who I've been with for almost a year. As much as people wanna say we are to young to be in love blah blah blah. Not true so I don't wanna hear it please. I've been in enough relationships and learned what a good thing is. I'm trying to live with him and his family. I can't get emancipated because I did leave highschool to get my GED and I don't have a job. My boyfriends parents would let me stay with them at no cost and would put me on their health insurance and help me with finding a job and going to school. My life at home isn't so great. My mom and I have never really gotten along because I would sneak out all the time and still do because she doesn't let me do anything, I feel like the only reason why I'm around is to watch my brother and sister. Now yes I have smoked weed and drank alcohol but is this something unusual? No. Plenty of teens do it and I'm not doing it cuz they are it's just the choices I decide to make. my boyfriend does these aswell but would never make me do them and I can handle being around people that do it and I won't do it. Oh and not to mention my mom hates his mom and his whole family so there's no way she would let me live with him. Please help.
