Why won't he talk to me in person instead of Text Messages?

so there's this guy i like right now were sorta friends i guess because he just got out of a relationship and he's so quiet so its hard to talk him about anything and i don't wanna get too personal but at school we barley talk in person but whne it comes to other people he's all loud and outspoken and then when it comes to me he's all kinda quiet? i don'y get it
