Is he into me as I am into him?

So I have this guy friend and we have been good friends for awhile since he is in my main group of friends. We have always had the relation of joking around and making fun of each other but lately hes been really different. I developed a crush on him a couple of weeks ago because we spend so much time with each other in school since we have a few cles together. In the mornings we used to walk to homeroom together whenever we would be around each other but now he looks for me every morning. He is always walking with me and even in homeroom whenever he can he comes by to talk. Also, he is always holding my arm and hugging me.To this point other people have noticed how we are inseperable and him waiting and looking around for me. ANd before when walking we never ran out of things to say but now hes always silent as if waiting for me to say something. DOes he like me? the thing is hes not the type to admit if he likes me or not if I don't say so first but maybe i might be overyzing things and maybe mistaken.
