I told him like 5 months ago to leave me alone. I made that very very clear. He has me on Facebook but I don't use my Facebook account. I only know he sent me a message because I put facebook in my spam emails. He always stares at me and follow me in school but he randomly text me on social media sometimes. What does he possibly want from me and why won't he just tell me in person? Should I open his message or just leave it and never read it?
