It takes two to tango. Abuse is the responsibility of the abuser. No matter how annoying or difficult one's spouse or children are, that is never an excuse to abuse and hurt them. Women abuse their husbands just as much as the opposite. Generally, when there is abuse, it is the wife who is abused by her husband.
Wife abuse is one of the main reasons for women to be seen in hospital emergency rooms.
When women hit or scratch, it is often in self-defense. If the abuse isn't physical, it isn't really so serious. We know that words can wound more deeply than blows. Emotional abuse kills the spirit. Furthermore, physical abuse is always accompanied, and often preceded, by emotional abuse.
