Gooood actor...??

i told this guy that i like him before break and he didnt answer me anything on the subject. now we're back to school and he is acting like nothing happened. like , when i went round him and his friend, he stopped me to talk and then he wanted to hug me, and as i didnt want, he pulled back. and after a while, he tried again so we hugged. it wasnt that we were too close friends before...but we used to do this once in a while. now im confused if he is just acting to be nice ( which would make him GREAT actor) or is he trying to hint something els??
