Does he have a thing for me?

There's this guy I've been friends with for five years now, and we go to the same summer camp. The bad thing is that he lives in a different state than me, but it's not too far. We started being friends in 2006, and he spent all his time with me and we talked a lot. He even let me take pictures with him and his arm was around me in all of them. The year after that, we were sitting on a couch with a bunch of friends and he let me rest my head on his lap. Then I sat up and was sitting close to him, and I leaned my head on his shoulder and he kind of shyly put his arm around me. He also asked me to dance, and gave me his email. Then the next year he still hung out with me a lot and always hugged me before going to bed (its a one week summer camp). We havent seen each other for a while, but he gave me his phone number, skype and new email address and added me on facebook. We talk every week on facebook and we could talk for hours. He and I have so much in common and he tells me about himself a lot and asks me questions about my life, and compliments me (mostly on my pictures). What do you think? Has he liked me for a long time?
