I never stopped loving my alcoholic boyfriend and I never stopped having compassion. Detaching doesn't mean we must stop loving someone or stop being compassionate.
Detaching doesn't mean we have to end the relationship or accept unacceptable behavior. Detaching means we learn how to stop focusing on what our alcoholic loved ones are doing with their lives and start focusing on the things that bring us joy.
Perhaps in addition to looking for bread in a hardware store, you misunderstood the meaning of detachment.
I believe that initially when we're confronted with unacceptable behavior on the part of our alcoholic loved ones it is normal to express anger, displeasure, and ask our partners to change.
I think normal ends when we fail to realize that the methods we've come to rely on again and again to force our alcoholic loved ones to change aren't working, but still we keep on trying the same thing again, and again, and again.
In my opinion, that's when normal ends and insanity begins.
