had,
All this says more about her than it does you. I believe alcoholics are so guilt ridden that being around sober people makes their behavior stand out more.
Yes, when I set boundaries other people will probably be angery if their behavior has become unaccectable to me.
You must keep the focus on you not her. IF you are her best friend she will have to learn to accept you as you are not as she'd like you to be.
You can still love her and care about her but please don't give you reailty away.
