<human>: My boyfriend is finishing his masters degree, which is why we've been mostly long distance.  I've seen this as a light at the end of the tunnel now that he's finishing up this december.  He visited me this weekend, and he's telling me how he's been so inspired and knows exactly what he wants to do.

He's studying environmental engineering, and he moved to Saskatoon, Canada to do his masters because he wanted to learn more about how water pollution is caused and why we're getting more and more of it, instead of just learning how to treat it.  He's become so inspired in ecological and environmental water systems, that he now wants to do a PhD in the subject!  But he told me he wants to learn more about water resources in areas without much water, so now he wants to apply to the University of Melbourne, in australia!  He wants to do a thesis on sustainable water supply in arid countries.

Not only will we be long distance for another few years, but we will be across the world (We're both from Denver), and in a different time zone!  I want to support him, but this is kind of a blow to my hopes that we'd finally be together.  He knows I'm shocked, but not really that I'm upset.  We haven't talked about this much other than him telling me that he really wants to do this, and we'll keep in touch like we have been.  But with him being across the world, it'll be almost impossible for me to ever go visit him :(

Is it worth staying together?
