I want to stop being friends with my best friend? She is just too untrustworthy.......?

She is not a good friend. Just because she is there for you does'nt mean she is a good friend. Stealing from you, bitching about you to others, that is not called a best friend. I guess you should just stop caling her your best friend. Tel her that you are really hurt. Tel her whatever is in you mind. Let her know about what you think and how you feel and if she just doesnt'nt accept it and tries to change things, i gues there is no point caling her you best friend or even a good friend. You value this friendship a lot, it shows from you actions- you trying to confront her so that she changes, you hav'nt broken this friendship til now, but what has she donw for you til nw? dtealing from you, bitching about you..I suggest you change you best friend. =)
