<human>: So, I've been living abroad. In the past few months I got romantically involved with a friend. He went home to his country a month ago, I'm going home to mine tomorrow. I visited him for a week and after a couple of mis-communicated discussions about what to do I've come to the conclusion that we both wanted to discuss long-distance but were too afraid to put ourselves out there. Now we're texting but he's not being very responsive although he reassured me before I left that he really likes me and promised to come visit me in my country.

I get that this situation is probably doomed and so I'm asking for help to get over him because my chest just feels like absolutely horrible and I feel completely lost and empty and like I don't want to do anything but see him again. I don't want my parents to see me like this but I've never felt this way after something ended before and I don't know how to handle it. Every forum I've looked at so far gives advice for being dumped or how to move on from unrequited love, someone who cheated, etc. but nothing for my situation. It's hard because I know he likes me still and there are lingering promises for the future but nothing solid enough to satisfy me.

Additional information, I know people who were able to overcome the distance barrier and are very happy but I don't foresee that happening for us because I don't speak his country's language and I can tell he'd never leave it.

Could you distill the essence of the text into 1-3 sentences?
<bot>: version: girl likes boy, boy likes girl, they date, they're separated by distance, they still like each other, girl feels so horrible she needs to get him out of her mind.
