and you think IF you have this talk with her, the result will be..........?
People would LOVE to have the kind of life she has, nice house, 3 cute kids, great car except she has, from what you share, a serious addiction problem. which could care less about how awesome her life is, or how cute her children are, or that she has children at all....she knows what she HAS in her life....still ain't stopping her.
nice things don't stop addiction.
kids don't stop addiction.
cars don't stop addiction.
YOU can't stop HER addiction.
