What comes after the smearing campaign? What's next?

After serval years I finally decided to end it with my N, I found out he was cheating on me. It quickly went from him cheating to him falsely accusing me of cheating. So now that I have chosen to end this because of something he did I find myself being bullied. He is going around telling whoever he can including my family and friends that he caught me having an affair. It's gotten out of control. I am letting him get it out of his system because I have read that there is just no winning with a N. My family is aware of him having a personality disorder. They see how insane he is and sounds. So for those of you who have been through this, what can I expect next? Is this the final stage? I know he's trying to ensure everyone around him that it was me, not him, and that he's a victim. I am fine with that. I just want it to all end. We do not have any ties, no children together. What happens next? Thank you for all the guidance.
