Moooving out ☺️☺️

So my boyfriend wants me to move in with him and his family because mine is so disfunctional and me living at home is all forced by threats and he hates the fact my parents are doing that to get their way. I'm 17 and my parents think I have nothing to do with him and have made defamation of character against him and basically tried to destroy our lives. I want to leave home but don't know how to go about it. Anyone help? It's ergent.
