There are tons of sites about npd and when breakups happen folks throw around npd as the culprit with their ex conveniently being affected by npd. Listen, I thought my ex had npd too. Then I realized they we were all going about things wrong. It is a trait, not a disorder. We're all capable of it. Some due to improper nurture and others on account of choice, struggle with it indefinitely. My father made a choice and I decided to exercise my right to choose by logging off npd abuse recovery sites, cutting off his supply and working on myself so that his behavior wouldn't impact me so much. Didn't take the pain away but it refocused me and took a ton of his power away, which for a narcissist is a huge blow. I also accepted responsibility for enabling him and sitting in victimhood. I encourage other non narcissists to do the same.
