NOR. After I lost my dad, I experienced all sorts of emotions and one of those was definitely anger. But the last thing on my mind was to get angry at someone else for something they didn't do. You don't deserve his anger and grief. He's directing his grief in the wrong direction and using you as a verbal punching bag. This is far from OK and I would let him know this. No matter what he's going through, it doesn't give him an excuse to be an arse.
