I was very nervous but I did go, and managed to share my story with the other people there.
They were all lovely, and had stories to tell of their alcoholic loved ones that were far worse than anything I had experienced, and I did say to them that I was not even sure that my dh was an alcoholic, just that he was a problem drinker whose drinking habits had impacted negatively on our marriage.
It was gently pointed out to me that Al Anon is for people who are affected by someone else's drinking, be they alcoholic or not, so that made me feel a bit less of a frauf for being there!
I must say that I did find it helpful, and I will go back, but I do wonder how do they actually teach you, in real, practical terms, to detatch with love and to let go etc It all sounds very spiritual but no actual structured advice on what to do, or how to cope with the binges etc..
Maybe that will come further down the line. I suppose I have at least taken the first step in putting my own needs to the forefront, and not letting this issue of drink dictate my happiness or emotional stability.
