I'm wondering? Many of the children suffering through parental separation and divorce experience parents arguments (and with the knowledge of brain science -experience the limbic irritability of seeing the parents angry faces and aggression towards one another). Many children are used as go between messengers between parents and it is not rare for me to have a parent in a divorce situation ask me to write a note about how the opposite parent is negligent in front of the child of both parents! I think in a way you could definitely be dealing with more that one ace - for example a parent angry about a divorce taking that anger out on the child, experiencing anxiety or depression, and having less to provide for basic needs --- these would make 4 aces! I don't have specific data but I can see a domino effect where multiple dysfunction lead to divorce and then to subsequently further dysfunction, chaos, and adversity.
