The Day You Said Good-Bye

When you said good bye,I swear I was going to die
I thought about what we had and think what was I thinking?
I regret every time I said I love you,it was just a waste of breathe
I have not one clue what it means to love again,you were my only one
I gave you my all,while you gave nothing in return
I trusted you with all my heart,all I got back was a slap in the face and a lonely heart
