stalker

So an old friend of mine, I cut him out of my life. We work together, but he doesn't work saturdays. I told him we're no longer friends days ago. He literally came to work today, just to talk to me. Followed me everywhere, then proceeded with "I'm going to block you on Facebook, so you don't stalk me. Have fun with your controlling boyfriend". Funny, my boyfriend isn't controlling, and he's always been jealous of my boyfriend. He would tell me to break up with him, even though he has a girlfriend (who's cheating). My boyfriend is the sweetest ever, we even have a kid together. I just told him I didn't care, but he kept coming at me like "oh, I never liked you, you were a great friend but I never liked you, no one cares about you" and some other shit. All because I told him that I don't want him and his stalker girlfriend around me. I don't need that negativity. I'm happy without him and his controlling whore. I don't get what his problem is. I respectfully said "nothing personal, but I'm respectfully backing away from the friendship. I don't need this". Then he started that! Talk about stalker.
