Why do you use the same dagger over and over?

You know it hurts me.
You know it does not help you in the long run.
So why do you keep shooting yourself in the foot?
You know it hurts me.
You know there is more to this world than black and white.
Thousands of colours between your silly spectrum.
So why do you keep painting with the same brush?
You know that I see every colour.
You know who I am.
You tell me that you love the person that I am.
So why do you keep telling me how wrong it is what I do?
You know that my beliefs are important to me.
You know that I love you.
You know that I want to make this work.
So why do you keep stabbing me with the same dagger?
It hurts more every time.
One of these times I will walk away with it.
I won't come back, and the dagger will be permanently mine.
