A respondent is someone who answers to a case in court. This term is commonly used in the civil sense, with a person in a similar position in a criminal case being termed the defendant.
The police will probably arrest the respondent for violating the order of protection. The respondent does not have to hit you to violate the order. If the respondent comes to your home and the order says he can't, then you can call the police. You also have the right to file a violation of the order in Family Court.
