Why not email him?
Ahh, okay. I'm sorry, that must be tough. It probably would be best to move on~
I am not trying to be mean, but a realist. He is in another country from you now and hard to say what has distracted him. I am sorry, but you need to let go.
I know and I am so sorry, maybe I am wrong, but I have been through this kind of thing before, people change quickly when they move far, far away. You should find a new distraction for yourself.
It takes time, things will get better for you.
