continuation from my previous post....

ok so here's the situation. I have known this guy for 4 years now (both are in late 20s). i have had feelings for him but never told him so.anywhow when he was moving back to his country (we both belong to the same country), i finally told him how i felt on his last night. we ended up at his place (no sex). Next morning i told him i wanted to give us a chance but he turned down saying long distances things doesn't works, even though he had feelings for me.Since it was a big blow to me, i didn't push him further on this issue.after a week of his departure he still messages me asking how everything is going. people have already replied back to my previous post that he has moved on and so should i....now i don't understand, even though he knows i have strong feelings for him why does he have to be in touch and that too days after he left? any thoughts? should i reply back to him? am i over-reacting?
