How do I end a friendship when she is so needy

[Bluegem7]

Has anyone tried to distance themselves from a longstanding friend who has narcissistic behaviour? When you've already told her that you're friendship has run it's course and you need to move on. When she writes to you asking to meet up (you haven't replied) she turns up at your work and asks if you can meet up. You feel sorry for her because she has no friends. How do you let her down gently? Or do you just be blunt?

You have ended the friendship but she isn’t listening. This sounds like stalking. You really need to go the police.

Kinder to be clear. “I don’t want to be friends any more but I wish you all the best. Please don’t contact me or turn up at my work or home. Take care.”

Yes, you just reiterate your message. The friendship has ended. She is not to show up at your workplace or home. You won’t be engaging further.

I've sent her a polite message reminding her that eighteen months ago I said our friendship had run it's course and for me nothing has changed and I'd appreciate if she'd respect my wishes. Ended with 'best wishes'. She read it and blocked me. Yaaaa!
