I agree with Impurrfect..you need some loving detachment.do you go to alanon or naranon..my daughter is a recovering heroin addict and it REALLY has helped me set boundaries, worry about myself, let her live her own life and deal with all the consequences.I thave also paid alot for rehabs (not that much!) and absolutely think it's fine for you to be done paying for his treatments..he has the tools, it's up to him to use them.I really suggest alanon..they don't get tired of hearing about your problems like other do and can help you move on in a way that's loving and healthy.
