A person doesn't have to be involved with alcohol in their past, their present, or their future to insert themselves in a negative or bossy way into somebody else's business. Don't we all know of people that have done just that who didn't drink at all !
So her recovery is not just about alcohol.
I have two sisters, one that is extremely bossy, and one that has very narrow view of the "truth" in life with a big T. Both I keep at the required distance. One drinks a normal social amount, the other never drinks.
What I do with all relationships is assess their weak and strong points and limitations. Each relationship is handled accordingly. When I get a phone call or correspondence, I think about it for awhile to see what the motives are. If I smell bad fish, I respond not at all, or in the limited way that protects myself from ulterior motives.
I have to do this with my sisters, else they bulldoze over the top of me, or manipulate me.
Not gonna happen!
