Books: A difficult or dangerous ex
The most crowded and least trustworthy shelf in the whole subject. Two of these are safety books rather than divorce books, and we say which. Every entry says who it is not for, which is the useful part and the part nobody else prints.
The buy links go to Bookshop.org, which supports independent bookshops. If you buy through one of them we earn a commission, at no extra cost to you. It does not affect which books are here or what we say about them — several of the books on this page we actively tell you not to buy, and the ones we rate worst are still listed with a link. Beside every buy link there is a library link, because a lot of people reading this site cannot spend forty dollars on a book this month and should not have to. How the rest of the site is funded.
A difficult or dangerous ex: 7 books
Ordered by how well evidenced they are rather than by how good they are, because those are different questions and the second one depends on who you are.
Annette Burns, Kevin Chafin, Bill Eddy · High Conflict Institute Press · first published 2020 · 200 pages
Bill Eddy is an attorney, therapist, and mediator who founded the High Conflict Institute; Annette Burns is a family-law attorney.
Teaches the BIFF method (Brief, Informative, Friendly, Firm) for writing texts and emails to a difficult co-parent without escalating conflict, with heavy use of worked examples and sample rewrites.
Read it if A co-parent who needs a repeatable formula for written communication with an ex who baits or provokes over text and email.
Do not read it if In-person or phone conflict — this is specifically a writing template, and doesn’t help with live arguments.
Practitioner experience, not research A practical technique developed through Eddy’s coaching and mediation practice, widely used in family-law circles but not validated by controlled studies.

Wendy T. Behary · New Harbinger Publications · first published 2008 · 176 pages
Wendy Behary is a psychotherapist specializing in schema therapy, trained under its founder Jeffrey Young.
Communication and boundary-setting techniques, rooted in schema therapy, for reducing conflict with a narcissistic person — how to be heard by someone whose self-protection makes them hard to reach.
Read it if Someone who needs practical scripts for lowering the temperature with a narcissistic ex during divorce and ongoing co-parenting.
Do not read it if Anyone in physical danger — this book is about managing communication, not safety planning, and self-diagnosing an ex as clinically narcissistic without a clinician isn’t its purpose.
Practitioner experience, not research Based on Behary’s clinical schema-therapy practice, not on population research about divorce outcomes.

Bill Eddy, Randi Kreger · New Harbinger Publications · first published 2011 · 305 pages
Bill Eddy is an attorney, therapist, and mediator who founded the High Conflict Institute; Randi Kreger writes and advocates on borderline personality disorder.
A strategy guide for divorcing or negotiating with a spouse whose behavior shows a persistent, extreme pattern of blame, rage, or reality-distortion — documentation habits, working with your lawyer, and calm written communication (BIFF).
Read it if Someone whose spouse’s behavior is genuinely extreme and disrupting the legal process itself, not just someone who is angry and difficult in the ordinary way divorce makes people angry and difficult.
Do not read it if Casually diagnosing an ordinary difficult ex. The personality-disorder framing is easy to misapply, and courts give no weight to an armchair diagnosis from a spouse who read a book.
Practitioner experience, not research Eddy’s authority comes from clinical and legal practice with high-conflict cases, not population-level research on divorce outcomes.
One caution. This book is frequently misused to retroactively label an ordinary difficult ex as personality-disordered. It is not a diagnostic manual, and treating it as one can itself escalate conflict.

Mason, Paul T. M.S. · New Harbinger · first published 1998 · 258 pages
Paul Mason is a psychotherapist; Randi Kreger is an author and advocate on borderline personality disorder, not a clinician.
A guide for family members and partners of someone with borderline personality disorder — understanding BPD behavior patterns, setting boundaries, and self-care while staying in or exiting the relationship.
Read it if Someone whose spouse has an actual clinical BPD diagnosis, or a strong, long-documented pattern consistent with it, who needs to understand and cope with that dynamic.
Do not read it if Using BPD traits as a checklist to diagnose an ordinary difficult ex without a clinician involved. It’s a book about a specific, clinically defined disorder, not a general guide to divorce conflict.
Practitioner experience, not research Grounded in clinical observation of BPD-affected families rather than a research study; widely used in the field but not a diagnostic tool for lay readers.

Lundy Bancroft · Berkley Books · first published 2002 · 419 pages
Lundy Bancroft spent years running counseling groups for abusive men, including co-directing one of the first U.S. intervention programs, and later worked as a custody evaluator.
A safety and pattern-recognition book, not a divorce-logistics book. It lays out the belief systems Bancroft observed underlying men’s controlling behavior in relationships, drawn from his years running abuser-intervention groups, and explains why couples counseling usually fails when real abuse is present.
Read it if Someone who suspects their relationship involved coercive control or abuse and needs help recognizing and naming the pattern.
Do not read it if Someone looking for divorce process help — there is almost nothing here about legal procedure, custody paperwork, or finances. It’s also not for someone hoping for a hopeful verdict on couples counseling; Bancroft is fairly deterministic that abusive men rarely change through therapy.
Practitioner experience, not research Built on Bancroft’s clinical and custody-evaluation experience rather than a controlled study, though it is widely respected within the domestic-violence field specifically because that experience is deep.

Bill Eddy · Janis Publications USA Inc.
Bill Eddy is an attorney, therapist, and mediator who founded the High Conflict Institute.
Explains Eddy’s own ‘high-conflict personality’ concept — a pattern of chronic blame-shifting — and gives general tips for managing interactions with someone who fits it. It’s aimed at workplace and family contexts broadly, not divorce specifically.
Read it if Someone trying to understand a recurring pattern of blame-shifting in an ex or relative and wants practical tips for limiting its damage.
Do not read it if Someone wanting divorce-process guidance — this is general-audience behavior-management material with no legal or procedural content.
Popular, weakly evidenced ‘High-conflict personality’ is Eddy’s own coined concept, not a recognized clinical diagnosis in the DSM. Treat it as a useful behavioral pattern to watch for, not a clinical category.

Gavin de Becker · Urano · first published 1997 · 372 pages
Gavin de Becker runs a security and threat-assessment consulting firm; he is not a psychologist or academic researcher.
A safety book, not a divorce book. It argues that intuitive threat perception is real and worth trusting, teaching readers to notice ‘pre-incident indicators’ of danger, drawn largely from case narratives out of de Becker’s security-consulting career. Only part of it concerns intimate partners; much is about strangers and workplace violence.
Read it if Someone with a specific, current safety concern about a partner or ex who has been talking themselves out of taking their own fear seriously.
Do not read it if General divorce readers with no safety concerns — most of the book isn’t about domestic situations at all, and it shouldn’t be read as a divorce-planning guide.
Popular, weakly evidenced De Becker’s threat-assessment claims come from his firm’s case experience, not controlled research, and psychologists have questioned how reliably ‘intuition’ actually predicts danger versus how the book’s narrative framing makes it feel that way in hindsight.
Open Library 4.0 from 6 ratings. Checked 2026-09-02.
Every title, author, publisher, year, page count and ISBN here was checked against a bibliographic database rather than typed from memory, and the candidates that could not be confirmed were dropped rather than guessed at. Ratings are shown only where we could see them at source, which is why several books have none — a blank is honest and an invented four-point-three is not. The judgments about what a book is worth are ours, they are opinions, and you are entitled to disagree with them. Tell us when we are wrong.
