I think I have a crush?

A week ago, I met a boy who came from another country for a trip and I got his number. We've been texting everyday and he's genuinely really nice, good looking, and smart. We're a couple years apart, and both of us are teenagers. I really like him and I think I have a crush on him. He sometimes says things that could imply something, but his mother tongue isn't English so I'm not sure. For the "What does your crush think about you" quiz, I got that he thinks I'm a great friend but wants to be more. What should I do?
