I feel about as low as is possible but getting away from their lies, cheating, manipulation and absolute refusal to self analyse on any level has to mean more than the illusion that was life with them.
Geting away from all of the chaos DOES mean more than the illusion! It takes time, but one day (not today,) you will know this as a fact. Just like you said... . stay away from her. The longer you do, the better off you'll be.
I'm sorry your mate had to hear all of her BS, but in a way, aren't you grateful for that? Sometimes, I think our friends think it's not as bad as we say it is.
And how in the world did she mistake your friend for you? Even that is kind of insulting!
