@ZAQWSXCDE,
I re-connected with my first crush not that long ago from Primary School. I'm engaged and he was Divorced. Didn't stop him flirting up a storm that I had to keep under raps until, he gave up.
Funny, he wasn't the guy I met at all, all those years ago
It's cool that he remembered you but get on with your life, long distance is extremely hard to do and neither of you are in a position to get acquainted, he's already moved away.
Plenty of fish in the sea, you don't really know him, it's cute to still have a bit of a crush.
Also remember we can't stop the Universe from doing its thing, if it's meant to be the opportunity will present itself again later down the track.
Good luck with school study and be successful at all you do, you only get one chance at that, but many in romance.
