If you’ve ever found yourself staring at a wall at 2:00 AM wondering why a person who claims to love you just spent three hours systematically shredding your self-esteem, you’ve probably had someone recommend a specific book to you. It’s thick. The cover is usually a nondescript, slightly dated design. But for anyone who has lived through the "walking on eggshells" phase of a relationship, Why Does He Do That? by Lundy Bancroft isn't just a book; it’s a manual for survival.
It’s been over twenty years since this book first hit the shelves, yet its relevance hasn't faded. If anything, it’s more vital now in an era of "therapy speak" where abusers have learned to weaponize terms like "boundaries" and "gaslighting" to further their own agendas. Bancroft didn't write this based on a weekend retreat or a few clinical trials. He spent fifteen years leading intervention programs for abusive men. He sat in the rooms. He heard the excuses. He saw the patterns that most people—even seasoned therapists—often miss.
The Myth of the Losing Control
We’ve been lied to. Honestly, that’s the biggest takeaway from Bancroft’s work. Most of us are raised to believe that an abusive man is someone who "loses his cool" or has an "anger management problem." We think he’s a boiling pot that just happens to overflow.
Bancroft flips the table on this. He argues, quite convincingly, that abuse isn't about losing control. It’s about gaining it.
Think about it. If a man "loses control" and screams at his partner, why doesn't he "lose control" and scream at his boss? Why doesn't he punch a police officer when he gets a speeding ticket? He doesn't, because he is in control. He chooses when, where, and against whom he directs his vitriol. This distinction is everything. It shifts the problem from a psychological "breakdown" to a conscious, value-based choice. Bancroft asserts that the problem isn't in his feelings; it’s in his belief system.
He believes he has the right to treat you this way.
It’s Not About Mental Illness
This is where things get uncomfortable for a lot of people. We want to believe that "he’s just sick" or "he had a bad childhood." While trauma is real and mental health struggles are valid, Bancroft is very clear: abuse is a social and political issue within a relationship, not a clinical one.
Most abusive men aren't mentally ill. They are entitled.

The book breaks down several "types" of abusers, though they often overlap. You have The Demand Man, who thinks his partner exists to serve his needs. There’s Mr. Right, who views every disagreement as a personal affront to his superior intellect. Then there's The Water Torturer, who doesn't scream but destroys you with calm, cold, calculated remarks. These aren't diagnoses from the DSM-5. They are descriptions of attitudes.
When we pathologize abuse, we give the abuser an out. We say, "He can't help it." Bancroft says, "He can help it; he just doesn't want to because the current system works for him."
Why Why Does He Do That? by Lundy Bancroft Still Offends People
Some people hate this book. They really do. They find it one-sided or argue that it ignores abusive women. Bancroft acknowledges that women can be abusive, but he focuses on men because the power dynamics and the societal "permission" for male-on-female violence are historically and statistically distinct.
He doesn't mince words. He doesn't offer "both sides" when one side is being crushed.
Critics often claim the book is too cynical about change. But if you’ve worked with batterers as long as Bancroft has, you realize that change is vanishingly rare. Why? Because to change, an abuser has to give up power. And humans are notoriously bad at giving up power. They might stop hitting, but they replace it with financial control. They might stop yelling, but they start using "the silent treatment" as a weapon. Bancroft warns that unless the underlying sense of entitlement is dismantled, the abuse just changes shape.
The Warning Signs Nobody Mentions
Most people look for bruises. Bancroft tells you to look at the eyes and the words.
One of the most chilling parts of the book is the discussion on how abusers "test" their partners early on. It’s not a grand explosion. It’s a small push. A joke at your expense to see if you’ll laugh or recoil. A "suggestion" that you shouldn't wear that dress because "other guys will look at you." It’s a slow-motion hijacking of your reality.
He also highlights the "honeymoon phase" trap. If a man is 100% mean all the time, you’d leave. The reason people stay is the 10% of the time when he’s charming, sweet, and exactly who you thought he was. Bancroft calls this "periodic reinforcement." It’s the same psychological trick that keeps people addicted to slot machines. You keep pulling the lever, hoping for the jackpot, even as you lose your house.
Real Talk: The Role of Therapy
One of the most controversial—but arguably most important—points in Why Does He Do That? by Lundy Bancroft is his stance on couples counseling.
Bancroft is explicitly against it in abusive situations.

Wait, what?
Yes. He argues that in couples therapy, the premise is that both people contribute to the problem. "You need to communicate better," the therapist says. But if one person is using communication as a weapon to manipulate the other, "better communication" just gives the abuser more ammunition. It validates the abuser's claim that his partner is "half the problem." Furthermore, many victims are too terrified to speak honestly in front of their abuser, making the session a farce.
If he is abusive, he doesn't need "marriage help." He needs an intervention program specifically designed for batterers.
The Myth of the "Triggers"
We hear a lot about triggers lately. "She triggered me," he might say after an outburst. Bancroft shreds this. He points out that an abuser’s triggers are often just the partner’s attempts at autonomy.
- You wanted to go out with friends? Trigger.
- You disagreed about the budget? Trigger.
- You were too tired for sex? Trigger.
When everything you do to exist as a separate human being is labeled a "trigger" for his anger, it’s not a psychological sensitivity. It’s a leash.
How to Actually Use This Information
Reading the book is a heavy experience. It’s common for readers to have "lightbulb moments" that feel more like a punch to the gut. You realize that the "misunderstandings" weren't accidents. They were intentional.
So, what do you do with that?

First, stop looking for the "why" in his past. It doesn't matter if his dad was mean or if his ex cheated on him. Plenty of people have horrible pasts and don't take it out on their partners. His past might explain his pain, but it doesn't excuse his behavior.
Second, watch for "the shift." Bancroft notes that abusers often get worse when the partner gains independence—like getting a job, going back to school, or becoming pregnant. These are moments where his control is threatened. If you see his behavior escalate during these times, take it as a serious warning.
Third, understand that you cannot "fix" him. You can’t love the abuse out of him. You can’t be "perfect" enough to make him stop. If the problem is his belief that he is entitled to control you, then nothing you do within that cage will change the man holding the key.
Actionable Steps for the "Walking on Eggshells" Phase
If you recognize your relationship in Bancroft’s pages, the path forward is rarely a straight line. It’s messy. It’s scary. But there are concrete things you can do to regain your footing.
1. Secretly build your "Reality Ark"
Start keeping a journal, but keep it somewhere he will never find it—perhaps a password-protected app or a hidden email account. Write down what happened. Not his version, yours. When he tells you "that never happened" or "you’re crazy," go back and read your own words. Protecting your sanity is the first step toward freedom.
2. Stop explaining yourself
This sounds counterintuitive. But in an abusive dynamic, "JADEing" (Justifying, Arguing, Defending, Explaining) is a trap. He isn't listening to understand; he’s listening to find holes in your logic so he can flip the script. If you’ve said it once, he heard you. You don't need to say it a thousand times. Save your breath for people who actually care about your perspective.
3. Consult the experts, not the "neutral" parties
Talk to a domestic violence advocate. You don't have to be ready to leave to call a hotline. These people understand the "Why Does He Do That?" framework better than your average family therapist. They can help you create a safety plan, even if you plan on staying for now.
4. Watch the "change" carefully
If he promises to change, look for the right signs. Is he blaming you less? Is he admitting to his behavior without adding a "but" at the end? Is he attending a program specifically for abusers (not just general anger management)? Genuine change takes years, not weeks. If he’s "cured" after two weeks of being nice, it’s just another honeymoon phase.
5. Prioritize your physical and financial autonomy
Abuse thrives on isolation and dependence. If you don't have your own bank account, try to start one. If you’ve lost touch with friends, reach out to one person you trust. Rebuilding the "you" that exists outside of him is the ultimate threat to his control, and your ultimate lifeline.
The brilliance of Why Does He Do That? by Lundy Bancroft is that it stops the spinning. It takes the chaotic, confusing whirlwind of an abusive relationship and lays it out in a cold, clear light. It tells you that you aren't crazy, you aren't failing, and most importantly, it isn't your fault. Understanding the "why" doesn't necessarily make the pain go away, but it does give you the map you need to find your way out of the woods.
