Friends- not all as they seem!

Well, another angry rant!! Just found out a friend *laughs hysterically* is not all she seems!! This certain person has taken it upon herself to give out personal details of my life (mine not hers) and blatantly slag me off all this apparantly to "fit in". Now i'm not mean enough to start bitching personally about her although I would have every right!! I just can't sink that low. I will do what real friends should do and tell her to her face and believe me it will be a long conversation,lots to say. Point of this being I can't understand why people who act in a way that says they don't like you would carry on acting like a friend. The one thing I pride myself on is being honest about who I am. I can be a bitch but I make an effort not to be and I certainly tell people what I think.

Thoughts and comments would be appreciated, xxxxx
