Let's address THE ELEPHANT IN THE ROOM
ABUSE IS ABUSE !! PERIOD !!
It doesn't matter if the ABUSER has Borderline personality disorder, Narcissistic personality disorder, Antisocial personality disorder, Histrionic Personality disorder or any disorder at all.
If you are being ABUSED GET OUT !! RUN AS FAR AWAY AS FAST AS YOU CAN !!
Then GET YOURSELF SOME SERIOUS HELP !! You need to find out what attracts you to unhealthy people to begin with.
If you are in an ABUSIVE RELATIONSHIP, GET OUT !! What are you wanting for ? Are you some kind of masochist? Are you waiting for your "LOVE" to find a new victim and dump you? Are you wanting to get pushed to your limit and SNAP? GET OUT !! Before someone gets seriously hurt besides you. GET OUT !! Before you lash out at your ABUSER or one of the people who they cheated with or yourself. Ultimately YOU LOSE.
GET OUT, RUN AS FAR AWAY AS FAST AS YOU CAN, GET YOURSELF SOME SERIOUS HELP and believe that you can have a normal, healthy, happy relationship with someone who truly loves and respects you.
Personality Disorders are developed over a lifetime of trial and error.
ABUSE DOESN'T HAVE TO BE TOLERATED!!
Maybe once those with Personality Disorder understand this they'll be motivated to change.
