I've only started thinking about this a few days ago, but I'm worried about. My partner (who I've been with for nearly 2 years) definitely displays some traits associated with NPD, such as a difficulty in taking blame and criticism and often reacting to these with anger, the tendency to be very critical of others, and often "fishing" for compliments.
However he does not show a lack of empathy, does not have an inflated self worth or need to be the center of attention, does not expect to be treated in a special way, have visions of grandeur and is generally respectful towards me and other people, acts caringly towards me and shows interest in some of my interests and in my self improvement, has shown the ability to put effort and make sacrifices for our relationship, and put up with my own faults. And even regarding the difficulty in taking blame or being very critical, when I confront him about it, he will acknowledge that I'm right, take the blame and apologize. Also if I'm being honest, the fishing for compliments is more aimed at the things he creates as an artist rather than at himself.
We're nearly two years in so it's definitely well past the "over evaluation" phase and if I'm being honest we're in a good place about 90% of the time. And for the record what I wrote here is exactly how things are, I'm not sugarcoating anything.
So what do you think? NPD or nah? I honestly think I may be exaggerating, but after reading about NPD and relationships with people who have it, my mind is whirling and I could use some opinions from people with more experience with such topics.
