He probably just doesn't like texting, I hate texting, especially when it comes to girls I'm interested in. Usually I try to get past texting to hanging out as soon as possible.
I would far rather talk face to face, he's probably the same way.

Some people are really bad texters. Its not a bad thing actually, it means that maybe they rather tlak things in person rather than text. He might be busy too, but give him another day or two to check how things go. If he keeps being boring you can always ask him if everything's good.
