bad time to love

So there is this guy I'm in love with,  he's older than me, we've met years ago, and I've been waiting for him to show me that he likes me back and a few months ago when I started planning my new life (I'm moving out), I just dumped the idea of us being a couple so from 4 weeks ago he started to show interested in me and started to text me things about he taking me on trips when he gets he's license (he's in a pilot program) and talking about how much he cares of me and  how much he'll miss me , I still like him so much so I have no idea how to react to this (I just have like 4 days to move out  to study outside my country and it will be too hard to have a relationship with someone who lives that far)
