Can a boy still fancy you if he doesnt speak to you for a while? 10pts for BA.?

this boy i fancy...he always stares at me in cl and tries to see past anyone in his way....he sometimes lightly punches me on the arm for no reason when he is near me and i dropped my pen and he picked it up and started drawing on his hand then he scribbeled on my hand for a laugh and it kinda sounds like he fancies me?...but he hasnt spoke to me in ages in the holidays....do you think he still fancies me?
