Op. You're much smarter than most of the people in these comments. By a pretty wide margin lol. You seem to have a good handle on the situation. I don't think you fucked up, because you shouldn't have to guard yourself from family, but now you know. It seems like you know the best course of action is just to live your own life and not really interact with them anymore. They obviously don't respect you, and people like that just aren't worth your time.
