I have been on my path of recovery for over 6 years now... and can vouch for the fact that detachment works - for you. The non-recovering alcoholic (both wet and dry!) will not take kindly to the detachment. It forces them to see the consequences of their behavior... and they will give strong "CHANGE BACK!" messages.
Their messages will escalate, and at some point, you need to say "Enough is enough."
I'm right there with you.
