Not a woman here, but I would still like to answer your question.
Most of the domestic calls I answered, were related to cheating, text messaging, and alcohol or drug useage.
But, some calls were entirely different, not involving any of the above circumstances.
Some domestic violence calls were related to assaults involving psychological disorders of one or both man and wife. A call like this, involves special intervention and not just a physical arrest. Most people, involved in this type of assault, are really not responsible for their actions. And, most of the couples are not arrested, but rather taken for a psychological examination. Most involved couples, later, do not even remember the events of the domestic assaults and released, after their examination. In cases likes these, its not the arrest that is important, its the calming of each party, in order to return them to their home,
