Blast from the past...

Hey all, so I dated a guy for my first 3 years of college and we broke up at the end of my junior year. I really just felt like I was missing out on something and wanted to be on my own for awhile. It wasn't the most amicable break up and we haven't seen each other or really spoken since then (2000). So out of the blue this guy e-mails me and I'm not quite sure why he has done this. I'm not the type to be friends with an ex and obviously we are NOT friends (there's some things he said about me that I definitely don't appreciate). So what's the deal? Do I e-mail him back or does that mean that we are friends if I do? Not quite sure what to do in this situation...any input is appreciated!
