You gave him your phone number right? Does he also have your address and know where you work/shop? It definately sounds like stalking behaviour starting. That is very scary. If anything out of the ordinary starts going on, please do not hesitate for a minute to contact the police. If you have any copies of emails, phone messages, or things like that keep them for evidence. Hopefully you'll never need them and this guy will just go away without any more problems.
