Love–hate relationship
relationship involving simultaneous or alternating emotions of love and hate

A love–hate relationship is an interpersonal relationship involving simultaneous or alternating emotions of love and hate—something particularly common when emotions are intense. The term is used frequently in psychology, popular writing and journalism. It can be applied to relationships with inanimate objects, or even concepts, as well as those of a romantic nature or between siblings or parents/children.
Psychological roots
A love–hate relationship has been linked to the occurrence of emotional ambivalence in early childhood, to conflicting responses by different ego states within the same person, or to the inevitable co-existence of egoistic conflicts with the object of love.
Individuals with narcissistic personality disorder or borderline personality disorder have been seen as particularly prone to aggressive reactions towards love objects, not least when issues of self-identity are involved: in extreme instances, hate at the very existence of the other may be the only emotion felt, until love breaks through behind it.
Research from Yale University suggests love–hate relationships may be the result of poor self-esteem.
Family and development
Love–hate relationships also develop within a familial context, especially between an adult and one or both of their parents. Love–hate relationships and sometimes complete estrangement between adults and one or both of their parents often indicates poor bonding with either parent in infancy, depressive symptoms of parents, borderline or narcissistic pathology in the adult child, and/or parental alienation in childhood. Parents who alienate their children from the other parent frequently suffer from borderline personality disorder (BPD) or narcissistic personality disorder (NPD). Children who experience parental alienation techniques by a borderline parent report a higher prevalence of low self-esteem, low self-sufficiency, insecure attachment styles, and higher levels of depression in adulthood.
