<human>: Give me the gist of the text in a nutshell

Background: We've been friends since childhood, got together last year and are very much in love. We're both now at university (a couple of hours apart) and seeing each other every couple of weeks. It's going to be difficult but we are both very committed to the relationship and have every intention of staying together. We communicate very well and believe that we can keep the relationship going.
 
Now, the course she's on allows her to study in North America next year. She applied for this course before we were together and really wants to go. I think she should go too; I know what an amazing time she'd have and how valuable an experience it would be for her educationally and personally.
 
But I can't help but feel like I want her to stay and study here instead. We've been talking about it a lot. She's extremely worried about it and is genuinely torn between staying and going. It's hard for me to enthusiastically support her going because with the timezone differences, the lack of any physical contact, and her having a totally new group of friends and lifestyle, I know that it could mean losing her and that is totally unthinkable for me. She's worried about leaving because she'd feel guilty for putting me through the anxiety/worry/general sadness of being in a very long distance relationship.
 
She wouldn't leave til August, but she has to decide fairly soon whether to stay or go. If she stays, I'd feel guilty for being the reason she missed out on such an amazing opportunity, and she might spend her life (or a very long time) regretting it. If she goes, though we intend to stay together and the relationship IS worth waiting for, we both know we could lose each other. We don't know what to do. She feels that although she has a lot to gain by going, she also has a lot to potentially lose.

What's the right thing to do? I know education and career stuff should come before relationships, especially while we're young, but it would be heartbreaking for both of us.
 
I'd just like to hear some thoughts on the situation
<bot>: Girlfriend can study abroad next year. I know she should go but we both know it might mean the end of our relationship and it's making it hard to feel confident in either decision. What do we do?
