Does my crush like me?

Whenever I text my crush he replies to it sometimes within half an hour, sometimes very quickly. But sometimes he takes hours to reply. And never initiates texting. We are friends in college. Though he initiates conversations in person. He playfully teases me too. One day he took a chair and sat beside me to talk. He also helped me with my project submission... Does he like me?
