I suspect that he really wants to break up, but feel too guilty or is too cowardly to do it immediately or face to face. If he truly wants to work things out, a break is not the solution, especially if it means your moving back home.
How can two people work on their relationship thousands of mile apart? And what happens if he decides he wants you back? Are you expected to uproot yourself again, possibly give up a new found job to return with no guarantees this will not happen again?
Moving here for another man was, I am sure, a huge decision for both of you, and one that impacted your life tremendously. It was probably vene a big sacrifice on your part. If after all that, he is not committed enough to the relationship, it's probably best to let go.
Besides, it will only make him resentful to have you hang on now that he has made his wishes clear. Perhaps one day he will realise his mistake, perhaps not. In the meantime, whether you go home or not, move on without him. Don't hang on.
That's my two cents' worth. Good luck and I hope things work out.
