If you have a friend in an abusive relationship, you may be tempted to "rescue" her or him. You may try to persuade your friend to leave the relationship by criticizing the abuser. However, criticizing the abuser may simply make the victim less willing to confide in you. Ask your friend how she or he feels. Express your concerns in a way that focuses on the abusive behavior rather than on the abuser. You might say, "I'm worried that you're getting hurt," rather than "That jerk doesn't deserve you." Let your friend know that she or he can always count on you for sympathy and support. That way, when your friend does feel ready to leave the relationship, she or he will be more likely to turn to you for help. The purpose of this piece is (a) to describe the consequences of abuse. (b) to discuss ways to prevent abuse. (c) to let teens know how to help a friend in an abusive relationship. (d) to list sources of help for abused teens.
