Hi Smarie, I'm glad you're no longer pretending everything is fine. I'm wondering whether he knows specifically why you're acting this way? You might be coming across as passive aggressive.
Have you spelt it out to him? Men in general prefer direct statements, and with an alcoholic you might have to be even more blunt.
Even better than withdrawing, next time he goes on a binge don't rescue him. The message will be loud and clear.
