To understand context of occurring and stopping of woman attacker’s domestic violence, this study analyzed a family therapy case of woman attacker couple. Under the premise which women’s domestic violence is also the result of interaction, this study analyzed the contexts and interactions of occurring and stopping of domestic violence in the perspective of Bowen’s Model. This study found that the wife’s violence was the result of low self-differentiation from her family of origin. The wife made a triangulation with her parents, and she became violent under the stressful situations. Especially the contexts of her husband’s blaming communication style which reminded her of her father who had always blamed her and her husband’s style of supporting his own mother made her violent. Through the realization process of these mechanism, the couple began new mutual interaction and differentiated from their own family of origin and they endeavor to stop violence managing the stressful situations. On the basis of the results practical discussions were made for the family violence cases of woman attackers.
