Did I just told him that I have a crush on him?

I have a crush on this guy and during the lecture break, i was sitting at my desk, while he was standing down there with his friends.
I thought that would be the perfect moment to oberseve him, since I could see him so well and he probably wouldn't notice.

Than all of a sudden he began to look at me. I got nervous and looked away by turing my face to the right. I than looked back at him and he was STILL looking. I again turned my face to the right then and looked after that to him and than he was STILL looking and slowly got his eyes off me.
