Girl texts/snapchats me every day but won't talk in person?

This girl (who apparently likes me, but idk) talks to me through snapchat or text every day. She would send me 7-8 snapchats in a row about her life but she doesn't send it to her other close friends.

But she avoids me like the plague in person. Even saying hi is a struggle, it's like I'm a total stranger.
It's annoying, she wasn't like that when we first started talking... what's going on?
