Originally, this book is aimed at living with alcoholics but it can be used by anyone who is in the situation which they find intollerable and need to detach from. It does not talk about actually leaving a person but to be able to live with them if thats the choice. I found it helpful in that it helps remove the responsibility of the family member or friend who will often try and help these people but this will cause them to become as ill as the alcoholic. This book is good in that it helped me stand back and look at the situation objectively. It would work in lots of different areas where the ability to let others just be is needed.
