This needs to be handled obviously. Donโt do nothing out of fear like many women do. Everyone here is right when they say tell the cops, family, the school, anyone and everyone. Make sure his true colors get out there so itโs less likely to happen to you or anyone else.
As a criminology/forensic psych major, donโt show fear or make yourself prey. Donโt be easy to take down. If you see him maintain eye contact, if he talks to you tell him to f*** off, be angry be difficult and be loud. It shows him you arenโt prey and if ppl are around, it shows them something is wrong.
