Welcome emma!
The longer I drank, the more I lost my true self. It's unfortunate, but a lot of us need an experience like you had to motivate us to get sober. The good news is that you're doing something about it and can use it for positive change.
When, where, and how much you share with your husband is up to you. I'd say give yourself some time and focus on your sobriety for the moment. Glad you've decided to join us!
