Why did he like you in the beginning? Well, you were POLITE, smiling, talkative and
 relaxed. You were keeping appropraite distance, you were focused on your friends
 and sharing your madness about travelling. You weren't thinking too much about him
though you considered him really cool.

What now?

He's on your mind way too much, you feel awkward talking to him and you badly want to
create something more then you could naturally get
at this moment.

So? STOP.

Live your life. Be polite, SMILE, talk, look and become relaxed again. Appreciate your friends,
spent time with them, make funny and crazy things. Be hard-working with your thieses.
 If you will get butterflies in your stomach while seeing him consider that
 as such a nice thing to feel. If nothing will happen more that's OKAY.
Be happy that you heard so many nice words from him anyway.
And the most important is he kind of cleared your head
from the past. For good.
