Kerri,
Thought I'd chime in on your story as it's very interesting. A few things jump out. First is the pot. I googled it and I see Austrailia has one of the highest rates of marijuana use in the world. This funny (and fake) article captures the general U.S. view of pot versus alcohol.
http://www.theonion.com/articles/alcoho ... -son,1368/This may be from a biased perspective, but it seems as though quitting your pot use should also be part of your turnaround plan. At the very least, it has been shown to have serious de-motivating side-effects on people. But, I'd love to hear your view (I've only tried it a few times in high school and didn't really like it). How does pot make you feel? How does it compare to alcohol? What makes it "better" than alcohol, in your opinion?
The second thing that leaped out is your marriage. It sounds like, even if you were to achieve 100% sobriety, you wouldn't have the ideal life you desire in your middle years because your husband turns himself into zombie-man every night by getting drunk (and putting himself at ridiculous risk for health problems at those levels). You reasonably fear making your way in life sober while your life-partner is drunk and watching rugby all night. So, my next question is, What would your ideal marriage look like? What would you like the typical night to look like with your husband? When I picture these empty nest years (not too far away!!), I picture vacations, long walks and exercise, hobbies and chores, going to daily Mass together (and, of course, sex!).
The situation you're in is unfortunate. He should really step it up and be leading the family and the marriage into the golden years, but he's not. But, remember, you can only change you. You'd be a fool, though, to let him drag you down from the person you want to become. Once you make the changes and become a better, more attractive person, he will hopefully notice and step up his own game or, in his mind, risk losing you to all the men that will find you much more interesting all the sudden. So, besides the NOT DRINKING (a non-activity), what things would you like to do to improve your looks, your lifestyle, your future?
PS I'm not saying you need to publicly answer my questions. Just throwing them out there as food for thought.
