The full range, not just the parts that show
Harm at home is not one behaviour. It is a family of them, and most of them leave nothing a doctor could photograph.
Physical, which is hitting, shoving, holding, blocking a doorway, driving dangerously to frighten you, and pressure on the neck. Sexual, which includes sex that happens when you did not want it, inside a marriage, and which the law in many countries now names. Verbal, which is not arguing but a steady account of what you are worth. Digital, which is your phone, your location, your messages, your passwords. Emotional, which is the silence that lasts four days.
And three that people almost never count. Money. Immigration papers. And religion.
