Guys, why do you reply with short and blunt texts?

I don't know if it's his personality or him being European, but whenever I text him, he always replies back with short and blunt answers. I'm quite a happy and positive person, so it shows in my texts... just not sure if this guy just doesn't like texting me? Even though he has shown signs that he likes me in person.
