WheredIGo…….since it seems to be fairly common---even in apparently healthy people, and it doesn't bother him and he isn't even aware of it....if it were me, I wouldn't even mention it.
I concur with Peaceful water, also. I know you mentioned making a "to-do" list for YOUR future self. Maybe, you could work on taking certain baby steps toward that.
I have found that if I do actually make a list on paper, I eventually get it done...lol.
I think that alanon would be a really good benefit for you. How much freedom of movement do you have---like does he watch your every miove?
You were concerned about whether he would get "mad" or not.
What is the worst thing that would happen if he gets "mad"? Will the locusts come? Will the cows stop giving milk? Will the well go dry?
****However, if he has ever been physically violent. you will need to handle your situation in a different way*****
I know that being so concerned for the alcoholic that it is a hard hard habit to break----one has to work hard on detaching.....
