Trauma bonding
A strong emotional attachment to someone who harms you, formed through a power imbalance and alternating cruelty and kindness.
What drives it
Intermittent relief from abuse creates a powerful pull, and the abuser becomes both source of threat and source of comfort; leaving feels more dangerous than staying.
How it shows
Work
Defends a bullying boss ('He's tough, but he really cares'); stays years in a toxic team; feels grateful for occasional praise from someone who regularly humiliates them; cannot imagine thriving elsewhere.
Relationships
Returns repeatedly to a harmful partner; minimises abuse to friends; feels intense longing after a fight; the good moments feel like proof of love. Friends and family become frustrated and pull away.
Self
Craving the other's approval more after they hurt you; telling yourself 'it's not that bad'; feeling more connected after a reconciliation than in calm times.
What tells it apart
Limerence: Limerence is intense longing that can occur without abuse; trauma bonding needs harm and power imbalance, and the person can name being hurt yet still feels pulled back.
Codependency: Codependency is a pattern of over-functioning for another, often in a non-abusive relationship; trauma bonding centres on attachment to someone who is actively harming the person.
Intermittent reinforcement: Intermittent reinforcement is the mechanism (unpredictable rewards); trauma bonding is the resulting attachment when the rewards come from someone who also harms.
A test
Ask whether the bond intensifies after episodes of mistreatment followed by kindness, and whether the person defends the other against evidence they themselves have described.
How strong the research is
clinical. Rooted in Donald Dutton and Susan Painter's small studies of abused women; widely used clinically and online, with little systematic research and a loose definition.
