My DH appears to be drinking a lot. He drinks beer and/or whisky every day and his measures aren’t small. This has continued for six or more years. He functions fine and manages to go to work every day. I’ve asked him to stop/cut down, explaining that I’m deeply concerned, but he becomes defensive or shuts down completely. I’ve now suggested that he monitor his drinking and write down when he drinks - just for his own benefit, not to be shared with me. I’ve also told him that if he doesn’t do this, I no longer want to be married to him, as I can’t be with an alcoholic. Am I overreacting? Help needed, please.
