Can you build a relationship with a person who has a score of 88/100 in narcissism test ?

Thinking of my ex relationship I’ve been wondering if I made the right decision leaving as I have ever truly loved her all my life. Most days I wonder if the abuses I received were exaggerated by me and if I could have hung in there .

I recall once she did a narcissistic test and scored 88/100, I didn’t even mind because I was in love .

I’m just curious people that know more about narcissists and narcissism, is it possible to have a happy life with someone that has that level of narcissistic traits?
