I live in North Carolina. I currently live with my step-dad and my mother. My father is in Florida. Our house is very unstable and not fit for me (18) and my 2 sisters (both 16). I'm planning on moving out with my 24-year-old girlfriend before the end of the year. I want to bring my sisters with me but I believe we might get some resistance from my mother. I know we won't have a problem getting on, especially with the help of our grandparents. I want to adopt or become the legal guardian of them. Is that the best way? Or should we try to get them emancipated? our last resort is foster care for them. We really don't want that but I also want this to go over as calmly and smoothly as possible. What do we do?
