Am I entitled to refuse to live with my fiancé's family after he had promised me an independent home, and what about his accusation that I don't love his family?

Your request for an independent dwelling separate from his family is your legitimate right, and it does not indicate your dislike for his family. Many wise people advise against excessive mixing, as it may lead to animosity. Aisha, may Allah be pleased with her, said: "Visit rarely, and you will be loved more."
