She suffers from Borderline personality disorder. The line: "Why didn't you fight for me? I filed for divorce to see if you really loved me." makes it obvious. My best friend was together with a BPD and she behaved the exact same way.
Normal girls just doesn't behave this way. Like Pook said in the DJ bible, try to quickly findout if they have a personality disorder then filter them out before they get close to you. Avoid them like the plague. If they do get close to you, they have a good chance to destroy your life with their mind games, like this chick did.
HPDs/BPDs act so nice before they get in a relationship with you, then when they got you into a "relationship" you suddenly realise that this girl isn't normal compared to the other girls you've been with. Something is seriously wrong with her. The further in you get in the relationship the more you realise how f**ked up they are in the head. A good advantage you gain by reading about these personality disorders is that their manipulation game is quite easy to decipher once you realise what kind of a disorder they have. The issue is most guys treat these girls like they were normal, which they are not.
