Do you think a relationship really has no recourse but to dissolve if either party refuses to join in a move?

I have a friend who is about to leave his country to start a new life with his GF in another. He is conflicted about the move yet seems more certain that he really wants to be with her. I think they could very well stay where they are, but that’s just my opinion. Other friends of ours are pushing him to remain where he wants to be, possibly forcing his GF to stay as well.

[ Also, in which other places on this Earth of ours would you never agree to move to, forcing you to possibly end your relationship with someone? More of just a fun question here. ]
