Yes, I believe the Cluster B Personality Disorders are almost always the result of severe trauma. So it's difficult to judge the person suffering from the disorder, but it's also necessary to put distance between you to keep yourself and your mental health safe. It's a fine line.

Your kids are also at higher risk for developing something similar as well (there is a genetic component), so hopefully they will be aware - and self-aware enough - to get help if problems arise.
