Have you ever had a relationship? Or had a solid conversation with people in stable relationships? Behavior and friends (friends being a marker of healthy social behavior) are more important than employment and looks by a landslide when it comes to establishing relationships. Employment matters only when trying to share resources, but not for dating. It's more important to have interests and show motivation and dedication to potentially get a job than having a job. Just ask anyone. If you have a job you hate and no motivation to get anything better or any interests in other activities in your life then it's gonna be hard to get a stable relationship with someone. With anyone I'd say.
Your dark triad is present in any abusive relationship to one degree or another. If you are specifically asking about outliers then go dig the true crime rabbitholes. Plenty there.
Yo dawg, I heard you like pictures
