Congrats.
To be honest, she's far less likely to leave you for being an A in recovery than she is for being an active A and finding out (which she would eventually - it would onky be a matter of time) that you've been living a lie.
You know, I'm willing to bet that this will be a great relief to you. The fear of being caught drinking plus the white-knuckling really will be draining your energy far more than you can know at the moment. (Take it from one who knows!)
Far better to like with integrity and not be a puppet to those fears and our addiction.
Have you looked up the meetings available to you?
