If you think divorce is the end of narcissistic abuse, you are incorrect.
When someone gets divorced, they are unmasking the narcissist. They are exposing the narcissist. The narcissist was abusing them prior to being unmasked. They were abusing them prior to divorce. What happens now is the narcissist goes into narcissistic rage. They will do anything to attack, destroy and continue the abuse of their target. They will make every attempt to isolate the target. They will use the children against their former spouse. They will do anything and everything they can to make life miserable for their target.
Post-divorce narcissistic abuse is actually greater than pre-divorce narcissistic abuse. It gets worse for the target/supply. The abuser will make every attempt to smear their former spouse to anyone who will listen. The worst thing that you can do to a narcissist is unmask them and expose them for what they truly are.
One of the most difficult things for people to understand is that they cannot have normalcy with a narcissist. The former spouse cannot communicate with them. Former family members cannot be trusted. And family members of the abused need to understand that they have to keep their distance from the narcissist.
The narcissist will use any and everything to attack their former spouse. If you have a family member who was married to a narcissist, you need to make yourself completely unavailable to that narcissist. You have to understand that your family member is still being abused by that person. So if you are communicating at all with the narcissist, you are participating in the abuse of your own family member.
