How ethical is it to call your ex a narcissist?

How ethical is it to call the man who drives the boat ‘Captain?’

Sometimes you have to call a spade a spade and when everything adds up, even if your best instincts had you avoiding the truth, what can you say?

Let's put it this way…we can make calling someone a narcissist ‘unethical’ when it becomes ‘unethical’ to be lied to, discarded like trash and manipulated to the point you actually think you are going insane….

Sound fair?
