Welcome to SR Dina
As an alcoholic I absolutely agree with the other guys - I know I was an alcoholic even tho I may not have drunk as much as my friends, I never got in trouble with the law and my bills were all paid on time. I still have friends and family who insist I'm not an alcoholic....
But I can see your concern that your relationship is suffering, and of course that's valid too.
Is your husband aware of your depth of feeling?
Have you considered counselling, maybe even couples counselling, to try and make sense of all this?
I also encourage you to visit our Family and Friends forums here - you'll also find a lot of people down there who've dealt with similar issues
