How do you end it with a pathological liar and a narcissist?
Since a pathological liar and narcissist is never going to be reasonable about anything, there is no point in reasoning with such a person; just refuse to have anything more to do with this toxic individual for any reason. If this person phones, just say that you won’t accept any more phone calls, and hang up. If he or she shows up at the door, don’t open it (and call the police if necessary).
