Love Is Pain, But Is Pain Love?

Love,
Why does my pain bring you pleasure?

You see me hurting
But
You do not know how much pain you put me in

You do not see the scars I see

You do not feel the aching running through me

You've hurt me so much
But yet I continue to believe that you'll never hurt me again..

So I ask you again

Why does my pain bring you pleasure?
