Isn't he supposed to love me?

Torn and broken
All the words he’s spoken
They break my heart in half
There’s only one concept I want to grasp
Isn’t he supposed to love me?

He will never realize
That he just brings tears to my eyes
They make me go insane
But that’ll never help with the pain

I’m always told that’s what they do
But doesn’t he see
He’s my brother and he should love me
