I figure there's hope and that maybe he is MLC or Bipolar. (He has been diagnosed with BP but refuses medication.)
Welcome to the board
MLC can mimic bipolar so the real question is has he been like this his whole life or just more recently. How long has he been diagnosed bipolar? Bipolar people will rarely take their meds and continue to stay on them, they would rather blame some one else.
No matter what you can not FIX him.
Get out and GAL. DETACH. Believe none of what he says and half of what he does. Have NO EXPECTATIONS. Take care of yourself, breathe, eat, sleep, exercise.
