I think you need to have a serious chat and get him to lay out what kind of commitment he is going to make. If you move in now, is he happy to move away in 2 years time? In 5? Will he support you (or even CAN he support you) until you find work locally since the job market there is bad?
IMO if you make this sacrifice, you're sending a signal that you're happy to do whatever he wants in order to stay with him, and don't expect him to make any sacrifices for you. Unless his job dictates staying where he is, and you've both discussed him being the sole breadwinner for a time in the future, it's not fair for him to dictate that you move to him or break up.
However, 2.5 hours is a hell of a long distance to be apart for a year, and if he's adamant that he won't move, then you need to if you want to stay together. In his mind, it's probably not an unreasonable request.
Is there anywhere half way between you that would be suitable for both of you to work? Somewhere that he's close enough to family to be involved with them, but that you have better employment prospects?
You need to have a serious conversation, and let him know how this request makes you feel. If you can see a future together, and he can see that future involving living elsewhere and is OK with that, then you can decide if it's worth the move. But if he can't see your future together being anywhere outside his current hometown, you've pretty much told us the answer already.
