i think you are going to have to figure out how to get back into your own hula hoop. if you keep
at the drunken bear, things might not go well for you. and you have moved from a position of helpful to hurtful.
if you don't like how he is when he's drunk, you have choices, other than constantly tell him what a waste of space he is. NO ONE wants to hear that and NO ONE is helped by it.
i GET what it is like to have your skull damn near split with fury and frustration and - this ain't no saint talking here. but the constant berating is abusive.....to him. and it does nothing to fix, resolve or change the situation.
you could always consider ending the relationship......that would bring immediate peace of sorts to all parties.
