I can't believe what I have done to you

With all of the pain I put you through
I'm surprised you have not left me yet
I treat you horrible, without even thinking
Yet you still stay by my side
Just taking all my harsh words in
Like blades piercing your fragile heart
Hearing my own words does the same to me
You must love me so much to go through this hell
And I must be Satan, putting you through this
Please forgive my cruel heart
You are in the process of mending my crushed heart
It must be because I love you so much to make you realize what I have been through

honestly, I LOVE YOU so much it put tears to my eyes writing this. I hope that you will forgive me
