Hate and Love

How is it possible to love someone you hate so much?
To care for someone who hurt you?
Who lied to you?
Who broke promises to you?

How is it possible to hate someone you love?
To want to kill the one who laughed with you?
Who read with you?
Who spent their time with you?

How is it possible to feel all of this?
How is it possible for me to love you?
How can I come to hate you?
How is it possible, that I really don't know?
