I am not sure that is true, if nothing else, it would build a paper trail should things escalate.
If you are not already doing so, start keeping a diary of any incidents including date, time and where it occurred. Not only will that provide you with an accurate record of events, it will also enable you to look for patterns in his behaviour and his routine so, if he tends to bother you, say, at lunchtimes, then you will know to be extra vigilant around that time and, if possible, take steps to avoid him. Knowledge is key
Make sure you are consistent in your reaction to him. Do not lessen his behavior by telling yourself that it is not that bad, don't allow yourself to feel sorry for him or blame yourself for his actions and do not think that you can have a conversation with him about his behaviour. Sounds harsh but, any of those reactions will risk encouraging him. Try as much as you can to ignore him but, be aware of your surroundings and the details.
Make sure that family, friends etc know that there is a problem so, they can let you know if they see him waiting for you and, if it makes you feel safer, consider sharing a "code word" with friends or family whereby, if you give that code word (either by text or phone call) they know that you feel unsafe and need help.
Try not to blame yourself
@fancicoffee13. Unfortunately the planet is littered with people who seem perfectly nice at the beginning but turn out to be absolute horrors. All we can do is hope that, in the future, we will be more able to spot them ... and run away fast!
Good luck
