There is this guy I went on a date with really long time ago (like probably 2 years ago) but it didn't work out. Lately, he has been acting really strange. He has been sending me text messages really late in the night (like 10:30pm and after) saying random things like "Guess where I am?" and I respond by saying " I don't care. I am sleeping" and I shut off my phone. The next day, I open my phone and I got multiple messages from him accusing me of being hostile and then follow up messages like "are you sleeping" which I already told him I am. I have also been receiving anonymous phone calls where the caller doesn't say anything on the other side in my voicemail. I suspect it is him because I only got this after I have given my phone number to him. I have no interest in this guy because I have already written him off since he played mind games with me before. The guy has no class whatsoever with women. Am I getting paranoid about this? Perhaps, it would slowly go away if I ignore his messages?
