What they found offensive in Message = 9 of Cups?

Pulled a 1 Card with a Question about someone who read my response message to them.

It really pissed them off.

I asked "What was most offensive about my Message?"

and I got the 9 of Cups. The "Wish Fulfilment card"

So are they mad I got to tell them off?

(A bit of background is it's an Ex who wanted to reconcile. I said no in a response message, and then she got mad. I thought the message I'd typed was pretty direct but not outrgith rude.)

In my response I did call her a "Narcissist."

Can the 9 of Cups mean that?
