(((hugs))) I know just how annoying that can be, and I am sorry you are dealing with it.
Unsatisfying as it is, with its total lack of immediate relief, all you can do is work towards accepting that this is who he is right now, and to hold on to your truth. As personal as it feels, it really isn't. He revises history in order to deal with himself, his addiction, and the consequences of it. He is drowning, and grabbing on to whatever he can. Just don't let him drag you below the surface with him.
Wishing you peace and patience.
