Can you report it? It sounds like he's borderline harassing you if he's following you to continue provoking you.
When i try to leave he just comes back around to harass my soul i think he enjoys pissing me off i just want to cry half the time because im so angry but i guess waljing away when i see him coming is the best solution
When that happens with me I try and remove myself from the situation so I can calm down and reflect on why I'm being irrationally bitchy. Sometimes it works sometimes it doesn't but it almost always gets me away from the person who is pissing me off..
