Cycle of Violence

Phase 1—building: increased tension, anger, blaming, and arguing

Phase 2—battering: hitting, slapping, kicking, choking, use of objects or weapons; sexual abuse; verbal threats and abuse

Phase 3—calm state (may decrease over time): batterer may deny violence, state he was drunk, say he’s sorry, and “promise it will never happen again,” returns to phase 1.
