How to heal from narcissistic abuse
Don't blame yourself if things aren't working.
If you are in a relationship with a narcissist, it is important not to beat yourself for the challenges that you face in your relationship. Your partner is dealing with a mental disorder that you have no control over.
What you do have control over is who you are in a relationship with, and your expectations for how you should be treated. Do not dwell on how things have changed, or think that the changes have been brought on by something you have done.
