If you've had to choose between 2 people u love, wich will it be? Your lover or your trusted best friend?

I'm only helping a friend out with this. My friend's best friend haves some work to do and had to move to England but my friend's lover also needs to move but to Japan, cause he needs to live with his family back again. Im helping her out. She's having a bad time to think. Help please...wich will it be? Or maybe...give a solution...an answer on how to bring my friend's lover and my friend's best friend to go to the same place.
