I did the worst thing of all The one thing I was taught to never do I knew better I think if I had to bet It'll be my biggest regret I'll probably never forgive myself ever I'm not as innocent in all of this as I wish I was Hate to admit my heart's all broken up All because I believed him when he said that he loved me Every time that he touched me Oh, I didn't have a clue I believed him when he said I was crazy For thinkin' just maybe those rumors were true He did the lying, the cheating, goodbye, and the leaving But the one thing that I can't believe is I believed him Can't believe I believed him (can't believe I believed him) I've always gone with my gut Except for this once How did I end up second-guessing? Yeah, that last time was the last time That I go outta my mind Swear that I've learned my lesson I believed him when he said that he loved me Every time that he touched me Oh, I didn't have a clue I believed him when he said I was crazy For thinkin' just maybe those rumors were true He did the lying, the cheating, goodbye, and the leaving But the one thing that I can't believe is I believed him, oh-woah Yeah, that last time was the last time That I go outta my mind Swear that I've learned my lesson But what I can't get past is how it looks lookin' back Without a shadow of a doubt, no question I believed him (I believed him) Can't believe I believed him (can't believe I believed him) Ohh I believed him when he said that he loved me Every time that he touched me Oh, I didn't have a clue I believed him when he said I was crazy For thinkin' just maybe those rumors were true He did the lying, the cheating, goodbye, and the leaving But the one thing that I can't believe is I believed him Can't believe I believed him (can't believe I believed him) Can't believe, can't believe I believed him Mm
