Song of songs. Friend of mine

I thought you're a friend of mine
and we are friends till the end of time
But then I just realize
That now I don't idolize
girls like you that make me cry
that left me alone and let to die

This is a poem for my friend in high school. We are friends until I learned to love her. When she discovered my feelings for her, she snob me and won't talk to me for a very long time
