Should Have Known

You're all alone I did this, I have no one else to blame;
you didn't know I was at risk, and its such a crying shame.
How you gave me all of you and wanted nothing else from me; and to make some time for you but I see you was lonely.
I couldn't see but now I know that I acted selfishly; I should have known that I let you down, caused you so much misery.
Forever to bleed.
All of the times you used to cry because I would let you down; I'm losing time, I should have tried a little more to be around.
But I didn't know that you were hurting, I was just too blind; anything I know for certain, another you I would never find.
I'm filled with regret, I'm gonna tip and throw myself in misery; now in your life I'll take more time, no more yearning without me.
But it hurts to think about you all by myself but now I see; I apologize for all the times I left you home waiting for me.
I should have known but now I know.
I'm gonna be there.
