What did I do wrong here? Is she losing interest on me?

The second answer, she answered it very short. Is it because she lost interest in me? I mean she always says hi to me when we walk past hallway and sometimes flirts with me, but constantly ignores my streak snaps in snapchat. What did I do wrong?

By the way I've figured out a way to screenshot the conversation without letting the other person notice it so dont worry if you guys think she will concern it
