<human>: Decided to post this under a throwaway. Long story short: We're both in our early 20s. Up until this point, things have been great for the most part. We had planned on marrying after finishing up grad school and getting stable jobs and all that. 

The problem: He's been offered a spot in an amazing med program at a university 600 miles away. It involves classes year round, and a year or two of studying abroad in Europe. He is ecstatic (an understatement), and I'm happy for him. 

...I just can't see our relationship surviving through 6 years of physical separation. I love the guy to bits, and I will not be so selfish as to discourage him from grabbing the opportunity by the balls and running with it.

I can't go with him, at least for the first few years. I'm a broke ass college student, and the city he'll be living in is fucking expensive. I just don't have the money now, and I won't for a while. I will, however, be able to afford the occasional drive/flight out to where he'll be living - maybe once every few months.

How would you prepare for something like this? We've been so close for so long, and now every time I see him I can't help but be saddened at the fact that he won't be around much longer. 

Do long distance relationships for such a long period of time ever work out?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My 5 year relationship will become a long distance one in 6 months time. I can't help but feel like we're totally fucked.
