Looking at it from a different perspective, living with an alcoholic/druggy for years could turn anyone into a harpy if they won't let go of them, now I don't follow them at all or watch the show but people that are in close contact with people with drug/alcohol problems tend to become very controlling over a period of time and oftentimes end up more sick than the person they are trying to control, trying to control an uncontrollable disease tends to do that to people. It's very easy to seem to be a nice guy when you're loaded (and enabled) all the time but no one can make a person become a drug addict, all you can do is allow it to get worse by enabling them. The basic riddle is why do only about 10% of the people who abuse etoh/drugs become addicted and the rest can stop or moderate?
