If a charges is filed you will generally get notice of it. Misdemeanors especially fall into this category, as the charges can be given to the person immediately by citation or sent to the person via mail (which is a summons to go to court) Either way, you will have to be notified of the charges in written form. Harassment, requires more than an isolated incident for the prosecution to have a case. Usually, there are multiple offenses that have occurred to the same person by the same person in a relatively short period of time. So, the verbal fight could be disorderly conduct (using offensive gestures, language, etc), but if you have not received a summons or citation by now, it could be due to the prosecutor not being including to file charges.
