You need to stay close any way possible. Be romantic and supportive-maybe send a love letter a day like they did in the old days. Skype as much as possible and chat online. Maybe send her some flowers occasionally and tell her how much you love and miss her. Being apart is v hard but you gotta keep your emotional connection strong right now and look forward to being home again. Its also a good idea not to make any female friends. Long distance makes you vulnerable so avoid temptation. Good luck
