There must be
a pathological fear of abandonment as well as the lack of empathy and the need and ability to manipulate and dominate others.The alienator may have a «splitting» personality which is a disorder that tends to deny them the ability to hold opposing thoughts, feelings, or beliefs about others.
«The conceptualization
of the core pathology
of BPD as stemming from a highly frightened, abused child who is left alone in a malevolent world, longing for safety and help but distrustful because
of fear of further abuse and
abandonment, is highly related to the model developed by Young (McGinn & Young, 1996)... Young elaborated on an idea, in the 1980s introduced by Aaron Beck in clinical workshops (D.M. Clark, personal communication), that some
pathological states
of patients with BPD are a sort
of regression into intense emotional states experienced as a child.
