ADMIRER or STALKER??!!

Received a call from a weirdo today. There is this "Uncle" that has been calling me for the past few years asking me to go out for lunch with him. He looks like a typical ok educated man in his forties and he pretty much looked harmless to me. I had lunch with him probably twice and he actually asked me to visit his family! OMG! Think that happened probably more than 3 years ago! Since then, I knew better than to entertain his calls and lunch requests, so everytime he calls, I will reply with a mono tone "I'm not free, busy" and I will hang up the phone. He stopped calling for a while and recently he started calling again. This time he said he got impt things to discuss with him that is inconvenient to discuss over the phone. Not willing to go at all, I asked him what is so impt. His reply was scary, freaky and shocking! He said he needs to discuss abt us, our future! OMG! I told him I'm married (btw I told him this few years ago to get him off my back) and he still can ask me am I sure? Am I just shy? Why I never tell him earlier after he has been calling me all these years! I nearly freaked out. Trica says he is a serious stalker! Better be careful around my office area in future. What a thing to happen to me! :(
