Get a Clue

Folks: I need your advice. Seriously.
Two years ago, I messed around with a - or so I thought at the time - hot Chicago DJ. It wasn't serious and, about six months in, I'd gotten bored with the situation and I just stopped answering the phone/calling him.
That was summer of 2007. I have only responded to TWO of his texts in the last two years:
One, a year ago, to tell him I had a boyfriend. I hoped that would get him to stop calling and texting me. The other, in January, telling him I was getting married. I figured that would do the trick. (I am not getting married, fyi. I lied). I was wrong.
About two or three times a month, he calls or texts (twice this week, one of them coming tonight) and he keeps doing so though he isn't getting any response from me. I haven't gone back to what used to be one of my favorite spots because he DJs there and I don't want him to see me and try to talk to me. His texts and calls are just too much at this point.
What should I do? Should I respond with a "LEAVE ME ALONE!" text? Or keep ignoring him? I thought he'd get the hint by now. What gives? Have other people gone through this? I'm curious.
Share your stories and advice.
