In my experience, narcissists are unable to even comprehend that they might be the cause of the issues, so talking to them does absolutely no good. They lack all the basic self awareness to even understand the problem, let alone attempt to fix it.
If someone has consistently abused you, they don't deserve a 'kind' ending to your relationship. They aren't interested in what you have to say anyways.
So, sometimes trying to reason with a narcissist or emotional abuser may do more harm than good. Set your boundaries and move on.
