If a person constantly invalidates your feelings is he/she a narcissist? If someone constantly invalidates your experiences and feelings does that mean they are a narcissist?

For example, if I am really hurt by someone and I go to a friend for support and my friend always invalidates everything I tell them does that mean they lack empathy? The interaction is always confusing and the fact of the matter is always deflected. They say things like 'I'm sure he didn't mean it. That wasn't his intention. etc.' Always!

Is that a sign of narcissism? They can't feel the pain themselves or they can't see it so they dismiss it?

But they say they care then impose what they think you should feel onto you.
Self-absorbed?
It really depends. first of all, the problem might be in the person who asks, maybe they really are super sensitive and what they are upset about is not rational.

Also you can never know from someones words that they lack empathy or not.
Some people are just tough, maybe he was in some back breaking situations in life that yours seem minor.

And also lack of empathy is just a small part of narcissism and is not a "only and only" determinant.

If you wanna see if others have empathy or not, you better watch their acts rather than analyzing their words. do they have criminal tendencies or ever were accused of criminal act? are they non-empathetic in their job? are they careless about others life situations? are they reckless? do they put others in trouble to get something they want? and so on.
