Why is he so quiet?

Anonymous
so I have been to talking to this guy for a while now online we talk for ages and it doesn't get awkward, but then when I see him at school he is quiet when around me and my friends and around me and his friends and when just around me he doesn't say much unlike online. What's going on why is he so quiet around me when I see him just with his friends he seams quite outgoing so yeah what's going on?
