Some guy is stalking me. Ten years ago I went to college with him and I last spoke to him 5 years ago. He would ring my number about 15 times in a row at 4am demanding to speak to me. I would just ignore him. Eventually I got tired and changed my number. A year passes and he's messaged my mother online even though he doesn't even know her name and he's only met her once ten years ago. He just put "I know your son, give me his number". I dunno what to do. Do I tell him to fuck off or I'm getting the police involved?
I used to go to clubs with him occasionally when I was in my late teens that's all.
