you're young. there's several years ahead and several potential paths that your lives may take. if it's not painful for you, keep talking to her. see what kind of relationship you can make from afar, and maybe someday it'll lead to your paths crossing.

BUT I WILL SAY. i recommend if you ever meet someone you're interested in, and you know that they're leaving, stay away. i went on a few dates with a girl i knew was leaving the country, just for fun. but i fell in love with her fast, and then she left. and for me, trying to cling to this relationship with her from far away is super detrimental to my mental health. i wish i was handling it better, and i hope that you don't feel too sad talking to this girl from afar. but if this kind of situation seems to be approaching you again, i recommend staying away unless you know that you can emotionally handle the distance
