One, he does almost ANYTHING just to be with or talk to you.
Two, he treats you like a princess. If he treats you differently from his other gal pals, then definitely there's 'something'.
Three, if he thinks everything you do is right. Four, (this is a cliche but this is the most obvious sign of hidden admiration) if he stares at you when you're not looking and when you catch him looking at you he suddenly averts his gaze away.
Five, it's all about body contact, baby!!!!
And Six, if he suddenly has that "change of attitude" towards you...Like, he stutters when he talks to you, he couldn't look at you straight in eye, you suddenly become the 'target' of his jokes(if he's a joker)....just anything unusual....;)
As to how you can tell him you like him....
If you're comfortable telling him straight out that you like him, then go....
If you're not, then you can always copy his "style" (from what I have stated above)!!!!
