I think your way off on this, more likely reason that someone will stay and try so long before saying I am done is because the addicted person cares only about themselves and their own needs and are very manipulative. I actually should edit this because in reading my comment I realized something, I am relating things to one specific person that I had to be done with for my own safety, would he have been a manipulative abuser without being a dope addict and pill popper..probably. I have been away from him for four years but as recent as a week ago had a call that he is once again in the mental hospital and I "HAVE" to go see him or he will kill himself. When I talk about addictions and how to help someone if relation to this person, I am sure I seem very bitter, but I DO believe you can not make someone change or get well if they do not choose that for themselves. in the context of my sons addiction, I did not give up on him but he willingly went to a rehab facility and wanted help, yes he messed up and was kicked out of rehab, yes I have trust issues with him, but I see he has and is making an effort to be and stay clean.
