I know your frustration at wanting to help, even if pushing sometimes.
I promise you that nothing you do or don't do, nothing you say or don't say nothing you feel, will make a lick of difference, she'll use or get clean on her own decision alone. Most of us here have begged, cried, yelled, pleaded, negotiated, manipulated and tried to love our addicts into recovery. All the love in the world can't save them, if it could not one of us would be here. Only they can do that themselves.
What helped us was taking care of us. In the end, that's usually what helped our addicts most of all because it was then they could learn their own lessons and live with the consequences of their actions. Who knew?
