The narcissist sociopath chose you because you are brilliant, bright, compassionate and caring.
He chose you because of all the qualities he lacks and expected you would prop up his low self-esteem and fragile ego.
You defeated the monster with your beautiful heart and you became stronger in the process.
So he has to move on to a weaker woman. One that will look past his lies and tolerate his abuse.
Keep your integrity and heart intact. This evil man chose to walk away from you because of your strength and because you saw through his fake personality.
What an amazing testimonial to your potential and spirit. Focus on that and realize that you fell in love with an illusion.
There are far better men in the world who will love and cherish you.
They will not lie and play games with you and blame you for their bad behavior.
They will take responsibility for their emotional state and will not expect you to nurse their fragile ego and be a scapegoat for their unresolved emotions.
