Do I actually like him?

So basically, there's this guy I've got a bit close to recently, he's just a slight bit older than me but literally the most respectful person I've ever met. He's literally the definition of a gentleman. He can tell when I'm feeling uncomfortable and knows exactly how to make me feel comfortable, respects me and doesn't force me for ANYTHING, shares the same interests as me, helps me and offers to help in literally anything. Basically just my type. And I'm in this confusion because I'm not sure if I actually like him. The thing is he's just that nice to everyone so i hate to think so much about it and get all giddy. He's going to Australia in less than 2 weeks and i can't stop thinking about, it's bothering me a little too much, and i make sure to not do anything wrong that might make him hate me, and i keep getting excited and smiley when we text each other.. and i know damn well he doesn't like me. I also know once he goes to Australia he will definitely find the perfect partner for himself and thinking about it is kinda hurting me. Does this mean i like him? I've known him for years but we got close just recently and I've never thought about him like this before ever.
