Guys, He says he is interested, but only gives me one word replies?

I met this guy at a party and he asked for my number. I thought he was cute, so I gave it to him. He and I started texting, but I notice that he gives me only one or two word replies. I thought maybe he was disinterested in me, but then he asked me on a date. I plan on going out with him to see if we connect, but I am just curious as to why he writes so little. Is this normal? Could he be shy? What should I do? Thanks in advance.
