I've got a crush, he always looks me in the eyes for a long period of time. Looks at me now and then, smiles and laughs whenever I say something and teases me. But when I told him that I had a crush on him and he said that he kinda noticed it... He said that he didn't 100% feel the same. Does that mean that it was all in my head or is it something else and I'm overthinking it?
