If a boy doesn't text you, but speaks to you a lot in person, does it mean anything?

Hi, so I recently met this boy at a school party about a month ago, and he gave me his number. Although we texted a lot in the first week, we've met up once just us two to watch a movie and hang out afterwards, and another time with a group of friends at a party. We get along really well in person, however we stopped texting and don't talk on facebook? Is this much to worry about? Or is he just that sort of person?
