Does he like me or just messing around?

So this popular cute kid in my school......lets call him drew...... anyway he has been sorta sending me these signals. like one day he put his arm around me and said hows it going? and my friend jess was like....you just d her. and he's like no if i d her i would have done the pelvic thrust then he did the pelic thrust. haha that was awkward. anyway the next day he like cornered me in social studies and stared at me the walked away. and my friend erin called my name in english cl. she said " hey chelsea!" and then Drew yelled "HEY CHELSEA!" and another day he was teasing me with some papers he had to give to me and was just messing around with me. He also did a bunch of other weird stuff. And today when I walked into social studies I put my bag on my desk then he grabbed me and took my bag to another desk and was like "leave the bag" and i was like "umm why?" and i took the bag and tried to walk away then he grabbed my bag, put it on the desk, grabbed my wrists and led me to my desk. then he walked away and i grabbed the bag and our friend caitlyn said "she has the bag drew!" and he looked at me and smiled then walked away. Does he like me? I really have no idea because he is one of the really popular kids and i'm just a regular popular kid. He is actually really nice and i like hanging around him. i also catch him glancing at me once in a while. please help! By the way we are only in 8th grade. he is 14 and i'm 13. Thanks and sorry this is kinda long. :)
