Randi Kreger draws on extensive new research to provide advice for successfully navigating life with someone who has borderline personality disorder. Step-by-step suggestions — many from users of the author's comprehensive website — help readers set and enforce personal limits, communicate clearly, cope with put-downs and rage, develop a safety plan, and make realistic decisions. Throughout the text are worksheets, checklists, and exercises that build on one another and enable readers to apply the suggestions to their lives.
