will try to keep this brief. Friend split up with ex a couple of years ago. They have one child, Joint Residency (50/50).
Ex is continually making proclamations in front of large groups of people in a formal environment regarding how she has 'escaped from her abusive ex'. No abuse has ever been proved, hasn't even been taken to court, and in all probability, friend is completely innocent. This is most likely a case of the ex trying to make herself look as good and innocent as possible in the eyes of her new friends (all the old friends are pretty sure of the truth anyway).
This slander is having a big impact on the emotional state of friend, as people who he doesn't even know treat him as if the tales are true.
Can anything be done to stop this slander?
