I can't shake the feeling of being hopeless

Since my ex is now abroad how will he ever change his mind about us? I just don’t know what to do or say anymore.

I’m at a complete loss.

If it helps, an ex of mine lived overseas. He appeared four months after I’d last spoken to him (through a mutual friend) asking them to ask me to unblock him. Ex’s don’t forget that easily, they’re still the same people you knew-- they’re not weird, blocked off emotionless robots, even though it might feel that way. Good luck!
