I agree, bradly, and glad you were able to keep your boundaries. It can hard for people who have chosen independent permanent abstinence, since it is opposite of many of the beliefs that are ingrained in our society about the nature of addiction and ending addiction.
I know that my family was very scared that I could not do this on my own, since they had actually been told that I could not do this on my own. I had to have some patience with them and give them time. They deserved that from me. Turns out the best way to get the people I love to believe that I would never drink again, is to actually never drink again.
