i agree with the idea that he's probably just checking in to see if you still have feelings for him (which you clearly do), and if he still has the ability to get you back (even if that's not what he really wants), or perhaps just trying to get laid.. It's also possible that he has matured a bit since the breakup and is just generally curious about your life and what's going on with you. With things like facebook and twitter, it's very easy to see what is going on in people's lives, and those types of social networking always tend to increase one's curiousity. I'll admit, I have an ex or two that I would like to check in on just out of sheer curiousity to see where their life has taken them and nothing else, no other motives, but I refrain, because I am in a happy, healthy relationship and I know my boyfriend would not be pleased if I started emailing my exes to see what's going on in their lives. It sounds like you are intent on responding, so if you chose to go down that road, keep it simple and brief. Say you are well, and spending time preparing for your exams. Do not mention that you miss him, still love him, etc, it will only add fuel to the fire.
