I met this guy in class. I could always catch him checking me out when I was not looking. Then one day I was sitting next to him and I told him that I was cold, he immediately lent me his jacket. We then started talking before the class and during breaks. I could feel that the way he looked at me was different, his eyes were always smiling. He got my number and organized some dinner. I could not make it so I sent him a message saying I was sorry. He then texted "let me know when you are free next." So I texted him back telling him when I was free. Then I heard nothing from him. Is he interested in me or not? I am confused.
