KEEP BEING WHO YOU ARE
Do not turn into a bitter or angry person. That is not you. Move on from the abuse and keep being who you have always been. Do not worry about the smear campaigns. Do not worry about what the narcissist and what they are saying to other people. Remember anyone that knows you knows who you are and they know what really happened between you and the narcissist.
When you want something to happen so badly and try forcing it, it almost never happens. When you let go of the NEED of it happening that when you will start to see results. Trust the process of life.
Trust that others will see what you see and even if some never do that has nothing to do with you. For your own sake, happiness, peace and contentment LET IT GO!
Remember forgiveness and letting go is for no one but yourself.
