Most Helpful Guy
It is possible that he didn't want to seem too forward.
What was your body language like? If there were no cues, then i might have done the same thing he did.
Both sexes need helpful hint, and honesty. That doesn't mean next time strip for him so he notices, but a few light touches goes a long way.
The guy does not have to be the one to make the first move all the time.
I would not give up yet, just try to make it more obvious that you like him. That could be from more body language or just straight up telling him you would like to be more than friends. No one likes rejection but we will never know until we ask.

If he had the opportunity and he didn't express any attraction or desire to be more than friends, that's a clear sign that he doesn't want anything more. Step a away from that relationship with grace and dignity if it's already hurting.
