If you felt like you were being stalked four years ago, then you probably were. I know people can change alot in that amount of time, but what makes people "stalkers" is a psychological element that they don't just grow out of. I have to err on the side of cautiousness and advise you you should be careful of this guy. And I would be very conscerned as to how he was able to find you. Some tips...save all of his emails and letters, keep a log of any phone calls and the subject of each, tell your friends and family about the guy so that they know not to give him your address, ect., and be firm with the guy. Let him know in no uncertain tems that his creeping you out and that you have no feelings for him. Tell him that you want to know how he found you and that you want no further contact. If he doesn't take the hint...call the police.

So sayeth a jaded ex-cop...
