It would depend on how they are contacting me and whether there is any history of violence or "psycho" behavior. (If they are psycho, how did I let it get this far before we broke up?) If I am concerned about violence, I make a police report and seek a domestic violence/stalking injunction. If they are not violent, I would have one talk with them to explain - in a nice way - that we are finished and it is best that we go our separate ways with no ill will between us. If that doesn't work, I might talk to their best friend (of the same gender as my ex) or a responsible family member to alert them to the problem and ask for their assistance. If the ex is in a profession like teaching or the military, police reports can have a negative impact on their career so I would use that as a last resort unless I was concerned about violence. And all of this assumes that I already have blocked them on my cell phone, social media, etc. and that has not cured the problem.

That's creepy and has potential to become a dangerous situation. If you're not carrying pepper spray already you need to. What does the person want to talk about? Is there a purpose in talking to them? Do they need closure?
