Would be nice if the world was that simple, however...
Legal proceedings should be governed by demonstrable facts not the "opinion" of the plaintiff.
The difference between romance and harassment is pretty much only in the feelings of the persons involved.
Otherwise, a defendant might only know if they were guilty of a crime retrospectively.
Legally, you pretty much only know if you were guilty of a crime when the jury returns the verdict, and that always happens long after the fact.
