Why does she treat me like this (can't put a word on it)?

Sometimes she talks to me happily.
Sometimes she disses me nonchalantly.
Sometimes she initiates conversation with me shyly.
When she walks past me, she reacts awkwardly or weird hello.

Later, I try to be friendlier with her, but she avoids me.

I am really confused.
