I need help

Sarah • love me love my dog
Recently I'm planning to confess to a guy,i think he's cute and gentle and maybe we will fit each other,but I'm not sure if he had feelings on me, most importantly, he will be leaving in ten days to another city for work(though it's not so far away), I would be regret if I missed him.but  I'm just nervous and afraid that he will say now to me, what am I going to do? Anybody can offer me some advices? That'll be much appreciated .
