My thinking was very much like yours just the other day! So I Goggled "stages of readiness" and found that I HAD to get out of the contemplation stage so that my action stage could have a chance at success. I wrote down a list of the reasons I wanted to quit, and that list was FINALLY greater than the list of reasons I wanted to keep drinking my wine. I keep the list in my wallet.
You can do this! You can find ways to work around all obstacles...including hubby's behavior...
