What does this guy trying to imply? Is he playing mind games with me? what's my next move?

There's this guy who is my classmate in HS 1 yr. ago. He seemed so nice to me.And he was popular in our campus and I was not. And he has a lot of gfs and his girlfriends are also popular and pretty of course. During that time I'm not even combing my hair and I'm not that smart. But I was shocked because still he asked me for a mellow dance during our prom. And now he keeps on sending me friendly messages and telling stories about his new school. And I think he enjoys chatting with me.And It was a coincidence that we both came from different place and move to US. And I'm 1 yr. ahead of him and he wants an advice from me. And he said on his email" till next time". what does it mean?The truth is that I have a big crush on him since 4 yrs. that I met him on HS. So what shall I do then? I'm confused.Because i don't want to fall for him very deeply for he might not catch me..He asked my number. So what does it mean? I need an advice.Help please.Thanks so much guys! I appreciate your answers

He likes you. Encourage him and see if it leads anywhere.
