1) Try and fix him. I know this is generally thought of as a bad idea, but I think it will be important for you to know that you did everything within your power for him in the event that something bad happens. When (adult) children lose a parent, the ones that mourn the loudest are typically the ones that were not taking care of the parent in their decline. The ones that support them in their declining years get to meet the sad day knowing they did everything they could for their loved one. I think this brings comfort by removing any guilt that someone might have. 2) If recovery is not an option, accept it. If you have run through all the reasonable things to be done to help your father from the outside, there is nothing left for you to do to fix him. Accept him for all his good characteristics and bad, and simply show him love. 3) Wait. Even if you were unable to fix him, he still might come around on his own, which is most likely what needs to happen anyways.
