I bet he likes you. With my crush, I never want to be the one to text him first. I wait for him to text me, and then I always reply. After he gets more comfortable texting you, he might start to be the one to make conversation. That's how it happened with me anyway.
If he's toting that fast then he is always there by his phone waiting for a txt from you which means he likes you but he may not want you to know it just wants to know more before he tries anything. Do you like him?
