Theodore Million proposed a subtype, called the " passive aggressive avoidant" or " avoidant borderline " where indeed these 2 seemingly polar opposite PDs come together. It's pretty rare, and most of the people were neglected as children. They avoid relationships at all costs unless they are absolutely certain they will not be rejected but then can have the same issues as borderlines maintaining those relationships.
I know Elle is a therapist, but not too many people besides psychiatrists keep up with all this. I dont have any training of course, but I've spent years studying personality disorders. Lets just say it's a , family , hobby.
And, I hope you enjoyed the cheesecake and it tastes better than the "tub of loneliness "
It was yummier than the tub of loneliness.
And, I'm not too sure it's all that rare a combo tbh. I think it depends on the population you're looking at, and also how exacting you're being in slapping labels on people. I'm thinking both of people I've worked with and, ot some extent, people I've known who definitely have borderline traits, but also pretty severe social anxity/avoidance of social situations where there's anyone potentially threatening (especially, anyone "new"). I think staying in the same basic geographic area during most or all of one's life makes these diagnoses actually quite compatible (ex. will be social with a select few people, but has made virtually no new friends since high school- last arena of forced socialization- has no desire to, is extremely socially avoidant beyond the extremely familiar, but is quit volitile in these familiar relationships).
