The Codependent Partner.
Sometimes only one partner has a mental disorder or addiction, but the non-afflicted parent is always going to be codependent to them. The codependent parent, whether they have a disorder or not, almost always suffers from PTSD or Complex PTSD. If both parents have a Cluster B disorder (which I think is usually the case), the one who has NPD or Malignant Narcissism is almost always going to call all the shots and dominate the other family members. If a Borderline is paired up with a Narcissist, the Borderline is almost always going to be codependent to the Narcissist, colluding in the abuse but also being abused themselves. Similarly, if a Covert Narcissist is paired up with an Overt Narcissist, the Covert one is going to be codependent to them and possibly abused. Such a scenario can lead to the Borderline or Covert Narcissist developing Stockholm Syndrome (identifying with and colluding with their abuser). Non-Cluster B codependents can also develop Stockholm Syndrome, because it’s a complication of C-PTSD. The codependent parent often (but not always) has a high degree of empathy, which is what drew them to the narcissist in the first place, in a misguided belief that they could “fix” them or they were led to believe that the narcissist could “rescue” them.
The Roles of the Children.
In the ACON community, there’s a lot of talk about Scapegoats and Golden Children, but there are other roles children can play in a family that are rarely addressed. In a two child family, most likely there will be a scapegoat and a golden child, but in larger families, there can also be a Lost Child, a Clown, and a Rescuer (codependent). It’s unhealthy for a child to be in any of these roles, but the Scapegoat and Golden Child role are probably the most dangerous to a child’s mental and emotional health, for different reasons. Even in a two-child family, the roles can shift back and forth (according to the Wikipedia article, families in which the children’s roles change and shift are called Balkanized families–this alludes to the constantly shifting loyalties and borders of the Balkan countries in Eastern Europe).
1. The Scapegoat.
Both this and the Golden Child role are the soul-killing roles, but for different reasons. The Scapegoat is the child who is targeted by the narcissistic (or alcoholic) parent. The parent often is able to get the rest of the family to serve as flying monkeys and gang up on that child, projecting anything they don’t want to “own” onto them. Like the sacrificial goats described in the Bible who were banished to the wilderness and tormented by villagers, the Scapegoated child carries all the shame the rest of the family doesn’t want to confront or deal with. All the unwanted emotions and bad qualities are unloaded and projected onto them, so the abusers don’t have to confront or deal with these problems in themselves.
Usually it’s the most sensitive child of the family who becomes the Scapegoat, because that child tends to be the Truth Teller, the only family member who can see the dysfunction and may even react against it. The most sensitive child, being the child who shows the most emotion, is also a threat to the narcissists in the family because emotional expression is such a frightening thing to them. In many, if not most dysfunctional families, the expression of emotion is not allowed. So the most emotional or sensitive child becomes the scapegoat, especially if they rebel against the dysfunction or criticize it.
