As hard as it sounds, maybe some tough "love" would help, not only her, but you too.
I know just as much as the next person who tends to be passive aggressive (
), the it might be easier to say it in writing. But write down your true feelings, in the kindest way possible. Try not to attack her behaviors and actions, but explain how they affect you in a negative way. I guess she could get really ****** at you and stop talking to you again. Or, if she has the ability to look past, she will see a friend who is trying to help her.
I really do wish you luck with this. But sometimes people dont change for the better if they are never faced head on with the way they are affecting the people around them. Because they are in denial, and they just dont see it. A practicing addict is selfish and self-centered. They cant see beyond themselves and their own needs. I know, I was there !!!!
Take care and keep me posted !!!
