If you want to believe reddit everyone's ex seem to have some kind of cluster-B personality disorder that only occurs in 1% of the population.I'm pretty sure the ex itself also diagnoses the person telling it with similar things.May also overlap with Trickster Girlfriend if she enjoys playing tricks on the protagonist and deliberately misleading him just for the fun of it.

She doesn't have any motivations of her own, unless they involve--you guessed it--helping the male protagonist.
