I'm sorry I'm not perfect.
I'm sorry I'm not the one.
I'm sorry I couldn't last that long.
I'm sorry you had to see me go through hell.
I'm sorry I wasn't good enough.
I'm sorry I couldn't make you happy.
I'm sorry I had to end it.
I'm sorry if I hurt you.
I'm sorry if I made you cry.
I'm sorry if you think you could have stopped me.
I'm sorry that you had to find me like this.
I'm sorry I faked that I was happy.
I'm sorry that I hid my true feelings.
I'm sorry for hiding behind a mask.
I'm sorry if I was ever mean to you in anyway.
I'm sorry for biting my tongue and never admitting I was wrong.
I'm sorry I couldn't be there for you every time you were down.
I'm sorry for ending it like this and never saying good-bye.
