Katie,
Its simple, As the Universal rule goes " BOYS ASK GIRL OUT" :)
You guys are on a good start, building friendship n bonding before asking out (for some people asking-out might mean kiss n bed) but, for u guys it will mean true relationship.....it really the best way..i guess :)

If he is looking for a relationship with you then yes,ofcourse he will ask you out soon ...or at least once all his stupid doubts abt u (if he has any) gets cleared in his head !
On the other hand,say, if he dint ask you out, then actually you are saved, because it will at least save your time instead of waiting n wondering abt him. Good Luck katie :)

just stop looking and start interacting with him katie, then only he will come to know about you... and if he really want to ask out he will not hesitate to ask if he feel that ur his friend....good luck stop seeing and start talking...
