It seems that you already tell him that you like him and he likes you back. To me seems like he is extremely shy or his skills on communication are really bad. Why don’t you try to get rid off his shyness. Perhaps furcas can help you on that.
Probably Dantalion can help you as well on this he can help you on knowing his thoughts.
Also maybe you should talk to him and actually tell him how you feel about him not just that he likes you. Perhaps after actually talking to him, regardless of what hi tell you about his feelings towards you. That might easy your mind.
Good luck!
