Guys and gals,help! i can't read his signals - is he genuinely interested or not?

wow can i just say something..i work in a hospital too and there is this guy who is behaving the same way this guy is behaving..wow what a coincident !! but the thing is he is a radiographer and i'm really infatuated with him....i just want him to be brave enough and say hie to me rather than just keeping Quiet whilst dying inside.. so my answer is DEFINITELY he likes you but he is not man enough to come and approach you...goodluck and plz can we get a feedback on what happened later,...cheers
