i met a guy from the navy!!

oh! im currently here in singapore for work. And last week i met a guy in a club he's from the navy and we really clicked.. we had a lot in common. he asked me for my number and wasn't really expecting that he will sent me a message and then we dated for 3 days.. we kissed and he tells me that he likes me he also asked me on how he can email me on my cellphone and i said " i don't know" and he told me that he's gonna find a way how to reach me he also told me that he is admiring me a lot. and when he left its been a week now and havent heard from him i actually emailed him twice but no respond yet. He was heading for the persian gulf and i don't know what's goin on with him now.. ive been thinking about him cant stand it! what should i do?? should i expect from his responds? or i should moved on with my life? some friends told me that navy's on mission has no time for themselves so they told me to wait and see... so i need your advice.. THANKS MY LOTTERS...
