How can you be abandoning her when she was out there all that time before you hunted her down and tried to get her into treatment? She managed to survive before you did that and she'll manage to survive now. When you finally realize, truly realize, that nothing you do can save her, then you will be ready to disengage from her. She knows how to get help if she wants it. As a matter of fact, I believe you said she was in treatment a few weeks ago but chose to leave. She is not ready to stop and that is HER CHOICE. It isn't something that is being foisted upon her. She had a choice and she made that choice.
