That's really admirable. Coming from a family of alcoholics, all functional alcoholics, I know how it can destroy you. My brother is in jail this week (short sentence) but what he did was partially because is disinhibition from drinking. Like I said he stopped but I'm sure resumed as soon as possible. I only hope it doesn't bring more heartache and I truly wish he would come to the place you are at. Sadly I doubt he ever really will.

You have a great plan. Now you need as much support as you can get. AA, SMARTrecovery (I think that's right), one of the other groups, whatever you can find that works for you and gives you support. You're doing a great thing for yourself.
