Abusive relationships, coercive control and repeated patterns of domination are the focus of Lundy Bancroft's books. Why Does He Do That? is his best-known book, examining entitlement, manipulation, intimidation and the beliefs that can sustain abuse while challenging explanations that reduce the problem to anger alone. Should I Stay or Should I Go?, written with JAC Patrissi, focuses more directly on evaluating a troubled relationship and considering safety, change and separation. Bancroft's prose is practical and strongly shaped by work with abusive men and survivors rather than by neutral relationship counselling.
