My husband was getting sick of our drinking long before me. Now we lead a very happy sober life together. Give him time and continue your great example. That being said, I understand your feelings or sadness. My extended family are heavy drinkers and/or alcoholics and my relationship with them has changed drastically. I feel a mix of sadness that they can't see the light and a misplaced guilt of sorts for needing to change and being different than the person that they have always known. I am definitely experiencing grief over this.
