Many years ago, I helped a bit with Bill Eddy’s first book, a landmark publication called Splitting that discussed and defined for the first time what it can be like to go through a divorce with a High Conflict Personality, such as a person with BPD or NPD traits. Here is a video from one of Bill’s series, discussing the analogy between splitting in politics, and the splitting that can occur in divorce.
Splittign behaviors can lead to conflict distortions, false allegations, and parental alienation, in a divorce and child custody case. It is always good to understand these phenomena, and to appreciate ways to manage them successfully in a divorce case.
