I've been in your shoes and for me it didn't work out. Married 22 years and I drank during the whole marriage. Like you, I never got into any legal trouble, held a good paying responsible job, and very rarely drank myself to pass out. Drank 4 to 5 beers every week night and more on the weekends. But I wasn't really there for my wife. At the end I was going through some difficult times at work and in the marriage and checked myself into rehab. I ended up 9 months sober and my wife wanted a divorce. That was 10 years ago.
I would strongly suggest you do couples therapy and have that question of can you make this work as the primary topic. Looking back my marriage probably would have ended even if I wasn't drinking. What ever way it works out I will tell you that life goes on and it can be a good life. It just takes awhile to get there.
Good luck to you.
