Why do guys reply with one word texts?

There's this guy that I really like and I think he likes me back. Last week he was asking my friend about me because he wanted to know if I still liked him. He asked me for my number on Saturday and we talked all day. That night he said goodnight and told me that it was fun talking to me even though I thought he was bored the entire time. He always texts back but only says one or two words. So i can't tell if he wants me to stop talking to him or if he just doesn't like texting. What do you think? And why would he text me when he has nothing to say? Also, he sent me a good morning text so is that a sign that he likes me?
