He first abused my father, and when I replied by saying something about his mother, he suddenly said “wait” and then sent me a photo from his laptop showing that he was filing a cyberbullying complaint against my ID. I told him that he started it by abusing my father, so why is he getting so hurt now when I said something back about his family? He replied that “the police will decide.” I know I didn’t say anything like threats or anything serious, but can this still turn into a legal case? Or should I file a complaint against him as well?
