The relevant question is ‘what does it mean when a person doesn’t express interest?’
And the answer, tautologously, ‘they’re not interested.’
The narcissism parameter is irrelevant.
The good news is that it should take you all of around eight seconds to find another man.
Just be kind and feminine.
Keep it simple.
Be predictably supportive.
If you try to be cute or snarky, it will backfire.
Just be a source of kindness and support, and they will come.
Men are not complicated.
