Has anyone here peacefully met a narcissistic ex?

My ex has a clinically diagnosed personality disorder and displayed many narcissistic traits during our relationship. It was emotionally exhausting, with manipulation, gaslighting, blame shifting and a lack of empathy. It took me a long time to heal after the breakup.

Now we’re considering meeting for a coffee. Surprisingly, I don’t feel attached anymore. I don’t believe she’s changed, so I’m not expecting anything. If we meet, I’ll be respectful and calm, but also much more cautious than I used to be.
Part of me sees that as a sign of healing and inner strength. Another part wonders if some people would see it as weakness.

Has anyone here met a narcissistic ex for a coffee or a walk after healing? What was your experience? Did it confirm your growth, or did old patterns come back?
