Abusers are not always hurtful. Many abusers have a likeable and loving side that makes their victims with only that the abuse would stop.
Many victims think they can change the abuser's behavior.
Abusers often threaten that the violence will get worse if the partner decides to leave. It's not always easy to admit that the relationship you are in is abusive. Some teenagers believe that their parents will react violently if they are aware of the abuse.
