I did the samw thing as you, except I gave him my home nubmer!
I was too drunk to remember my cell, but anyay. The guy called nonstop for a whole week. I swear, he called at least five tiems a day. My parents were like "give him a chance....he seems to really like you." Um, hello STALKER!!!!!! I say ignore the calls as much as you can. He'll EVENTUALLY get the hint. Best of luck.
