How to tell if this guy likes me?

I was with this boy Friday and Saturday and he was really chatty with me, he kept hugging me which he never usually does. He kept poking me jokingly too. When we were all just about to leave he told my mate to get me so he could say goodbye to me, he gave me a hug and hugged me tightly and snuggled his head into my neck/shoulder line. Is he just being friendly or does he like me ?? Help please !! Thanks :) x
