I thank you for your thoughts. It is nice to realize that someone else knows what I am talking about. I have been to embarrassed to confide in anyone that I know.
It has occurred to me that he must make his own way, and if something terrible happened to him, the authorities would be able to reach me. (right?). I suppose I should probably try one of those al-anon meetings. I have been reluctant to go, but I think that I finally feel overwhelmed enough to give it a try.
I just wish this was not happening.
