<human>: We met while both of us were abroad (i.e. I am from country A, she from country B, met in country C). We spent about 6 months together in country C and were "together" for almost 2 years, but after that trip, were only able to see each other about twice per year for about 2 weeks at a time. We finally decided that the loneliness of our LDR was just too much stress on our relationship, and neither of us was really excited about expatriating to get closer. 

I've been through break ups before. I know I could find someone else, given time. I have in the past; I can do it again. But a huge part of me can't get over how compatible we were. Just knowing that there is a person on the other side of the ocean that I could have a happy life with, if the circumstances were different, gets me so depressed. I can't just pack up and leave my career to get to her. As romantic as that seems, it is entirely unrealistic, and I can't expect any different from her. It just sucks. I miss everything about her. Even the micro instances that got me angry. On a macro level, those things make her who she is, and I love who she is. I don't want to find love in someone else that is similar when I know exactly what I am looking for is out there in a person that I already know and love.

Can you condense the text into a few key points?
<bot>: Ended the best relationship I've ever been in because of distance. Neither of us could realistically commit to leaving our careers and expatriating, and the stress just became too much.
