Ferry, for what it's worth, I don't see you as the bad guy, and I doubt that anyone else here will, either.
I'm in a similar situation: AW got drunk and broke her ankle two months ago. While recovering, she hasn't been drinking much... just a bottle of wine here and there that her drinking buddy snuck in to her while I was at work.
The Doctor released her to drive Monday. Where does she go? You guessed it... the liquor store. Last night she was plastered on Peppermint Schnapps. I guess her alcohol addled brain thinks it's not so bad if it smells like candy.
Whenever I confront her about the drinking, she gets defensive and says I'm making a big deal out of nothing. I've given up on the lectures; they don't help. She's disabled due to psychological problems, unable to work, so if/when I get disgusted enough to leave, I'll look like the bad guy to all her family and friends.
Hang in there. You're in a lonely, frightening place. I would imagine that, like me, you've been horrified to watch your wife turn into a person you don't even know any more.
There are people here who will offer great advice, even though I'm too much of a coward to follow it.
Good luck... keep posting.
