Thank you so much for the responses.
The issue is, I feel extremely guilty about abandoning him, I feel like if Alcoholism is a disease, just like cancer is a disease, is it fair for me to abandon him just because this is out of his control.
Another issue is that I was the one who suggested breathalyzer and that if he succeeds, I will give him another chance...If I back off now, he will never be motivated to quit ever again.
I greatly appreciate the advice.
God Bless You all
