Does a man get nervous when he knows the girl likes him but he doesn't like her?

Why do a guy would be nervous around a girl, start to fidget his hand, when he's not doing to same with other girl? What about a man that knows a girl likes him without she told it to him, does he get nervous? This same guy (doing all this stuff written above, fidgeting etc..) turns always his body into my direction even iif he's far away , makes some eyes contact, glances at me but never start talking to me and when I come to talk to him he starts fidgeting his right hand or playing with objects in rapid moves. When we're close to each other is not facing me but he's standing next to me. When I touched him on his shoulder, first he didn't make a step back but then he started to get REALLY nervous, playing with chair, fidgeting his feet and hands, moving a lot. What does that mean? Does he like me but is too shy? Or does he try to hide something? Or does he just not like me?

thanks for your answer !

But this man is my teacher and I'm 18...
I like him so that's why I asked
Because I think he knows I like him even if I didn't say anything
I thought it was for this reason he was acting nervous
