Glad you posted before you set off to drink at your husband. I sympathize with you about his behavior. My wife drinks so rarely it isn't an issue because she has never said she wants me to drink. I'm not sure what would prompt your husband to try to derail your sobriety except that he must not get it...get what it means to be an alcoholic.
But since it comes up only when you are arguing, I think he knows he's striking a nerve. Maybe you should be looking at your arguing and try to resolve those tensions and disagreements before they get to the "fighting dirty" stage.
