I think that if you really want to be with this guy, you will have to accept that you both have conflicting schedules and make time for each other whenever you can. You could also fill the communication gaps with phone calls, emails, text messages, or Skype during those times when you can't be together face-to-face. Ultimately, you have to decide if you can handle this or if a relationship like this will meet your needs several months down the road. I have friends with husbands who are in another country while serving active-duty in the military. If love is in the picture, love will endure.
