Guy texts me everyday but isn't asking me out?

Guy texts me everyday with flirty/teasing stuff. He'll open the conversation teasing about something he knows about me.

So far he has only asked me to hangout at our University but not outside of it. But he texts me everyday...?

What do you think? Shy? Is he trying to get to know me better just by meeting at school?
