A date from hell!!!?

I went on a date with someone I met on the internet. During our online conversation, I learned that he's a well-to-do lawyer who's looking for a nice girl to settle down with (okay, for the last time, haters, I am no virgin next door so keep the hateful words to yourself) Long story short, I gave him a strong hint that there's no future for us being together and I stopped returning his calls....BIG MISTAKE!! This lawyer is sooo crazy!! He keeps calling and calling and writing me emails (Girls, it's not just phone number, email too should be kept away from the first date) I wish I could just post some of his freakish emails here because they all read like "legal doents"!! What the hell should I do?? He's not stalking me but his antics are annoying. Help!!
