I agree that I suspect there could be relationship issues involved here, which may not have much to do with drinking. The thing is that stopping drinking is only the beginning. From there, many changes occur and we have to find our way.
My suggestion would be to plan to do something yourself, for yourself. Go to a movie you've been wanting to see or visit a friend. And, when the time is right, have a heart-to-heart with your husband and let him know what you need in the relationship.
