Does this guy like me?

Well i started like this guy, and i think he likes me back. Im to shy to ask, but yeah. He really acts like he does. One time when we were hanging out at dinner with all or friends from school, instead of sitting my the boys he sat right next to me and he started to poke me so i would poke back. haha and my friends sister was like "Awww!" and he just had a amused look on his face haha :) Also i know this is small but it was nice, he had one more piece of gum and i said can i have a piece? (i dint know he had only one) and he said well its my last one but. Sure u can have it :) and gave it to me. Haha we also talk on facebook and twitter a lot and once when we were at youth at church we were outside and i came up to him and i just played with his hoodie and i put his hood over his head and he smiled and i smiled and his friend said "Awww!" lol that's all i can really think of at the moment does it sound like he likes me or not?
