Its important how you act after getting dumped. If you keep trying you could come across as needy and emotional. You will get over him but you wont get over acting needy and emotional, it will haunt you for life.
Send him a text wishing him luck, tell him you will (pray, hope, send positive thoughts, whatever your thing is) that he remains safe and gets home ok. Thank him for his service and wish him well for the future.
Then see what happens.
