Right on.
Here's my take, in a general sense. She's a BPD/Narcissist kinda person. He, as you said, is also troubled.
She looks like a real-life Cruella Deville, & he reminds me of the troubled comportment & diction of one Marlon Brando. In the case of adults who otherwise have the means of independence, the dance of abuse is, I believe, a 2-person proposition. With each taking turns at the role of abuser & abused in many cases; with the abuser seemingly convinced, at times that they are actually a righteously vindictive victim, seeking retribution for past wrongs. It's a toxic worldview where the dichotomy is being either abused or the abuser. Seems people in this mindset are trying to work-out their past traumatic relationships with the other adult as the stand-in for that significant figure(s) from their past that laid the foundation for this bleak world view & their place(s) in it. Takes real work to transcend. Good luck to them both.
