If it is a family member, it is inevitable to stay away from him or her. We can just continue to keep on giving advices to them and try to give him or her a BIG lesson.
Those that like melodrama and stirring up trouble will not allow you to avoid them, unless you move so far away it becomes too inconvenient for them to reach you. What you cannot avoid you must grow a spine, and learn to deal with.
Just be civil with the person and avoid too intimate a relationship with the person even if they are your family. You can do one answer and question thing then after that you distance yourself from the person and divert your attention to other more important things.
