Since I went to inpatient detox, I had to tell my DBF because we live together and he was taking me in there. I told my daughter because my DBF convinced me not to keep secrets from her, and I told my best friend. When an old boyfriend took me out to dinner I told him I didn't drink any more, and no details. He didn't pry. That was it. They were all glad for me because they could see what damage it was doing to me. Just last week I told a trusted coworker, but nobody else. I don't think you need to tell anyone you don't want to tell. I will say, though that telling people I don't drink any more helps me to stay sober, because I know they are watching me.
