That is definitely an alcoholic tendancy. I understand he is not an alcoholic, but I think that people with this characteristic will go to any length to preserve their way of life. The A's do it when the codie no longer covers for them, buys the booze, bends over backwards to help and do things for them.
My XAH always used to blame shift like that. When I was truly done, but waiting to be able to move, he always blamed my family, especially the women, for filling my head with lies about him....He was desperate to maintain his life. That sounds like what your dad is doing.
