Does it cover relationships?
Yes — more than any other single theme. Six of the thirty chapters are about relationships directly, and the mechanism chapters at the front are largely about why relationships go the way they do.
The six chapters
What each one actually covers.
| Chapter | What it does |
|---|---|
| 2 · The favorite person phenomenon | One person elevated above everyone else, and what happens when your emotional state is set by their ordinary behaviour. The most-cited chapter in the book and the one readers most often say they had never seen written down. |
| 5 · Relationships as emotional regulation | Why using a relationship to manage your internal state does not work, and what it does to the relationship. This is the argument the rest of the relationship material rests on. |
| 7 · The relationship sabotage cycle | Ending or damaging something good before it can be taken away, and the stages that lead there. Uncomfortable reading and the most practically useful of the six. |
| 16 · Interpersonal effectiveness | DEAR MAN, GIVE and FAST — asking for things, keeping the relationship, and keeping your self-respect. The skills chapter of the group. |
| 22 · Relationships with healthy boundaries | Boundaries as a practised skill rather than a stance, including why they are hardest with the person you are most afraid of losing. |
| 26 · Advanced relationship skills | What changes once the crises have stopped — repair as routine, and the flatness that follows the intensity going. |
What it does not do
Four expectations readers arrive with that the book does not meet, stated so you can decide before buying.
- 01
It is not a couples book
It is written to the person with BPD. There are no exercises for two people, no chapters addressed to a partner, and nothing designed to be worked through together.
- 02
It does not tell you whether to leave
No decision framework for ending a relationship, and no assessment of whether a particular one is good for you. Those are questions for a therapist who knows the situation.
- 03
It does not cover abuse
Neither identifying it nor leaving it. If that is the live question, a domestic abuse service is the right resource and this book is not a substitute for one.
- 04
It is not written for the partner
A partner reading it is reading someone else's mail. The mechanism chapters are genuinely useful that way; the skills chapters assume the reader is the one dysregulating.
Related questions
What people ask once they know which chapters cover it.
Is the favorite person chapter worth it on its own?
For a lot of readers it is the reason they bought the book. It is chapter 2, so it arrives early, and the term itself is a community one rather than a clinical one — which is part of why it lands.
Does it cover friendships or only romantic relationships?
Both, though the examples lean romantic. The mechanism is the same and most of it transfers directly to friendships and family.
Will it help me stop sabotaging things?
Chapter 7 describes the cycle precisely, which is the necessary first step and not the whole job. Recognition plus the delay techniques does most of the practical work.
Should my partner read it?
The first seven chapters, if they want to understand what is happening. The rest will read oddly to them. There are reader-route pages for partners and loved ones on this site.
Is there anything for repairing after a rupture?
Chapters 22 and 26 both touch it, and there are dedicated guides on this site for the conversation afterwards and for repair across the following weeks.
Where should I start if relationships are the whole problem?
Chapter 2, then 5, then 7. In that order — the middle one explains why the first one is happening, and the third is what it produces.
