My thoughts are, the only person this will effect, is YOU.
Why bother?? You are just staying engaged with him, by 'telling' anyone. Let it go.....
as hard as it is..... just let it go.
It will rear it's ugly head all on it's own.
The only person you need to talk about - is you, and how you are doing, how you are copeing.....
I don't tell anyone anymore about my abf's addiction, It's not worth my breath....
I just talk here, to gain help for myself.
Best of luck to you,
Cessy
