Am so afraid i'm gonna be so heartbroken...but i really don't know what to do....HELP!?

i knew this guy for over a year...but since 2months we confessed our sentiments towards eachother...so we went into a relationship. I livein malta ...he lives in sri lanka..so yeah...far away. Please..i plead u, don't start saying it's plain craziness. We really love eachother...tell everything about eachother and did so many sacrifices to talk to eachother. We sometimes phone, otherwise we chat over internet. We used to caht all day long, now a lil less cos of his job and college. He wants to come here, but not now cos of the studies. He told me to find a work in like 1 1/2 years. However i'm not sure these days...should i continue to chat with him or not? i'm feeling i will get hurt cos i really really love him so much...but will we really have a future together? what shall i tell him?....he's muslim...i'm christian to make it even worse....please help me
