An addicted family member is still a family member, that no matter how much bad he does to you, he'd still have a special treatment from you. And in my own experience, it feels really different with your family member than with an individual you don't really know personally or emotionally attached to. As for me, I still give the proper respect to my aunt that should be given to an aunt despite all the bad things he did to me. I think in that way, I'm not pushing him farther and towards addiction. That's my way of helping her. It doesn't mean though that I simply forget the bad things.
