Rar, good for you on coming here to read posts today. I've got a similar situation going on at home. My wife still drinks heavily and she drinks my beer of choice so the fridge is always stocked.
I had to realize that I was making this decision for me. I had to really understand that I can't control anyone other than me. It's definitely tough quitting while your spouse is drinking, but definitely doable.
I think most days, my wife really wants to quit too but just isn't ready yet. Again, that's her choice and I choose not to drink for me.
Hang in there, you can do this!
