I assume then you live in the same community as them? Is there anyone, family or aquaintance that you do trust who can step in? I am just not sure what else that I can say other than I really feel for you. I have a younger brother who on the surface tries to be all helpful in public but who is a big turd in my life behind the scenes. I find myself pretending all is well for my father's sake even though my brother has been really awful. I have confided in people as to what has gone on but no one seems to believe me as what they see is the pretend character he wants them to see. It is revolting.
