Yea, I know that she's hurting her by providing for her ("If you teach a man to fish"... I know). I think it's easier said then done, at least for my mom she went really soft (she wasn't with me lol). My sister was psychologically evaluated, they said she has a mentality/maturity of a 12 year old (drugs fried her brain I guess). When she is in rehab they tell my Mom what my sister needs, my Mom goes and gets it. When she gets home, again, she should charge her rent or something (my sister definitely would not make it on her own financially). After I graduated high school I had to pay my mom rent, I don't know why the same rules wouldn't apply.
