After dating for six months, she told him she was going to be out of the country for six months and, consequently, should break up. He replied that he loved her and, no, they shouldn't break up. She sent this message the next day.
You said that your intentions were for something more serious from the beginning. So were mine. I, like you, was not looking for a months-long fling or anything of that sort. But I’m afraid that we have come to different realizations. I’m sorry that I cannot return the same feelings back for you but I’m just not feeling it. You said that we should go w/ what we feel (not how long we’ve been together) and I ultimately agree (even though I still believe that time also plays an important role b/c you can’t love or even like somebody until you get to know them better). You (rhetorical you) don’t know in advance what’s gonna happen or how you’re gonna feel months down the road and I had no way of knowing that I would come to this conclusion when I first met you. I like you a lot and we’re compatible and get along for the most part but something is missing. It is what it is and I have to be honest with you about my feelings. I’ve been thinking about this ever since I started considering out-of-the-country placements for this fellowship and it’s not just about the distance. I’m sorry, my intention is not to hurt you in any way, but I have to be honest with myself and with you. I hope that you understand.
