wow, this is so odd reading this as I am in the EXACT same situation.. mine goes to support groups, doesnt touch a drink for 4 weeks then relapses and binges with alcohol and cocaine.
he sees me as a nag as well, I find myself analysing him, every move he makes, everytime he leaves the house.
He too makes promises and breaks them, letting me down, alcohol comes first as soon as he has 1, he becomes so selfish. Which is so unlike him.
I have left and packed my bags because of it so many times.
I dont know what to do either, he binges and is mentally unwell for days after and hates himself for it then it happens again, its so draining.
