Why does my ex gf keeps posting these things?

She broke up about a month ago but we didn't unfriend each other on facebook. She posts "moving on" quotes from tumblr, but later that day she will post lyrics to sad songs?

Songs like fine frenzy - almost over

is she trying to make me realize see that she's really moving on purpose? or is she hiding her pain?
