I agree with sarahsweets - the term "narcissist" is very easily thrown around. I'm not saying that this individual is or isn't a narcissist (we only have a one-sided account about this person and I've never spoken with them), but it is a word that is easily thrown around to describe people.

Narcissism is a very trendy topic right now, with many articles being released about it. So of course the term "narcissist" and amateur diagnoses of NPD are more and more common these days.

Labels shouldn't be the primary focus here. This individual displayed some behaviour that you did not like and was incompatible with what you wanted. So it sounds like you two are not compatible for any sort of relationship, because you want your boundaries to be respected and he is not respectful of your boundaries. That's the primary focus.
