true, it can...

though i personally am very good until i can't be anymore - both in friendship and love, and i had a sort of stalkers, both among ex-friends and ex-partners, who knew full well that they deserved no explanation at the time i decided to cut them, yet playing all surprised, and some still gossiping about me years after like we are still in a relationship though in some cases the quarter of century had passed! and still trying to put a question mark where i put a period a few lifetimes ago. (so i heard and i cut those who informed me, too, btw. i would never allow conversation to go in this direction that i can hear a gossip about my friend).

so if ghosting can be a narcissistic trait (it can of course), insisting on someone explaining themselves can be a narcissistic trait, too, depending on the persons involved and specific situations. imo.
