Yes, your mother can make you come home. If she is willing for you to go live with the other family, a guardianship must be created to protect the family as well as to give them the authority to act as your parent.
Yes. At 17 you are not of legal age to make that decision. If she agrees she can go to court and agree to a guardianship from her to the adults. Your boyfriend cannot be your legal guardian.

Parents deserve your respect.
