Girls and women are much more likely to be victims of date rape or domestic violence than of street crime. Getting out of an abusive relationship is often difficult and can be very dangerous. In fact, the most perilous time for a woman is when she tries to leave an abusive situation. It's much better not to get into one. Her safety is more important than the breaking of any family rule.
Assaultive behavior is always the responsibility of the offender.
It is never her fault if she is abused. Give your daughter the information she needs to protect herself.
