Tex,
You did nothing wrong. In an odd way it may be a good thing that your mate is aware that is friend saw him in all his glory. I dont know if it will help, sometimes it did and sometimes it didnt. There is the old expression "hate the sin love the sinner" think about that.
I am not trying to minimize how you feel. You have every right to be ticked and ticked royally. In my case it would help the anger or the hurt when i thought of that saying and ask myself "is this what she would want'? The answer of course is no. Who wants to be an alcoholic? It just sort of kept MY sanity.
