My partner’s mother has Narcissistic Personality Disorder. It has affected her dramatically throughout her life and throughout her relationships. I want to be supportive, and its hard. Do you know anything about NPD?

A diagnosis of NPD just gives a name to a pattern of behavior. It is not an excuse for that behavior. The brutal truth is that narcissists are horrible fucking people who wreak emotional havoc wherever they go.

It’s fine if you want to be supportive of your partner’s mother, but you don’t have to put up with her shit just because the DSM has a label for her flavor of chaos.
