Personal relationships are highly complex. People experience feelings differently; they misinterpret conversations or actions; they fight and break up only to reconcile later. Because of these complexities, someone could wind up crossing a line and engaging in criminal harassment.
Criminal harassment is harassing someone or causing them to fear for their or their loved ones' safety. There are serious consequences for this offence, so you should know what misconduct can look like and how you can respond if you are accused of this crime.
