Are you asking whether you should move with your partner, or have it be a long distance relationship for a while?
This was posted over a year ago. What did you decide? Or was this more of a theoretical/philosophi cal question?
Whether or not your question was situation-specific, I think that one should only move if they're absolutely certain that their significant other is what is right for them. Additionally, how much of your life is rooted where you currently live? Do you have lots of opportunities where they are going? How long have you been together? Do you know anyone else in your hypothetical future location? If you break up, can you still support yourself in unfamiliar territory? Will anybody help you there, other than your significant other? There is so much to think about. Ultimately, it is about what is best for you, not your relationship.
I'd be interested to hear what you did, if you were asking for advice when posting this a year ago.
