While they are drunk is it the truth that comes out or just BS from all the self hate they must be carying around.
Who knows???
I think what's important is
why are they saying what they're saying?
What reaction is he trying to elicit from you? Is he looking for you to say "yeah, I'm tired of your drunken a**, you're right, you're worthless" so he can get into a fight with you? Is he looking for you to say, "oh, honey, no, you're not, you just have a little drinking problem, you're
really a great person" so he can feel better about himself? Or something completely different?
I find that the best thing I can do when AH is drunk is
ignore him and go about my business. Fold the laundry, go for a walk, and respond to his rants with a non-committal "oh"...
Because no matter what he says, it's just a hook to engage me in whatever alcoholic verbal dance he's wanting to initiate at that particular moment.
