I care for my Brother. Recently we had a situation where we were at a friend’s home and he decided he wanted to leave. It was within walking distance to home however I don't think he is safe walking around alone. I insisted he stay, and he got very obstinate, refused to let me drive him home and then insisted he was walking home anyway. I handled it badly but felt I needed to assert myself. Things were said which resulted in my brother slapping me. I need help to become better prepared to handle situations like this moving forward. Are there any books, videos or classes anyone can recommend for me?
