i have seen this time and time again....he must detach himself and walk out....his recovery is a stake!!!
i do not except unexceptable behaviours anymore....and disrespect...i walk out...
in times of CHANGE...its the hardest thing to do...people change and the alcoholic gets sober...its a triger, and its normal....its what you decide to do with it...
you enable the behaviours and stay...you are grown adults...you have choices...
my two cents
