"If your teenager came home with a black eye or a broken arm, you would do everything you could to separate your child from the person who inflicted those injuries. But physical violence is just one form of relationship abuse, and not the most prevalent form. In the United States, one in five teenage girls experiences physical or sexual abuse while dating, while one in three experiences emotional abuse. Emotional abuse is harder to see— it leaves no physical scars— so it’s essential that parents and teens learn the warning signs."
