Does he like me? I'll answer all your questions if you need?

Okay, I'm in ninth grade and I go to a homeschool enrichment program. There's this guy in my theatre class, we'll call him Ben. At the beginning he was so funny, and after a few hesitations he began to talk to me. He's never really all that serious, always hilarious and shamelessly strange. Throughout the year we've become more and more friendly toward one another, and he always teases. My friend said when I missed class one day he didn't make any jokes. Now that our showing is nearing and the school year has passed he's been talking me more, never really all that serious of discussions. Once I sat across him in the lounge while skipping band and he talked to me the whole time, being funny and grinning and carrying on the conversation when we went quiet for a moment. Sometimes he just grins at me and a few times really recently I've caught him staring at me, or looking at me when he tells a joke. Yesterday he was walking around outside when I was waiting for my dad by the curb and just came over and sat ten feet away, starting to babble about how his mom probably forgot him again so I sat next to him and we talked until my dad came. He said, "Welp. See ya." And then I said, "Okay, yeah, see you, bye!" And he said "Bye." Once, before saying it louder. It was so cute. I really like him.

Should I ask him for his Skype or something? What should I do? He doesn't have a phone so I can't ask for his number.
