Vicente Fernández's "Juro Que Nunca Volveré" is a powerful declaration of a broken heart's resolve. Our singer has been hurt, and he's not shy about admitting it! He tells his former love, "Podría volver / Pero no vuelvo por orgullo simplemente" [I could come back / But I'm not coming back simply out of pride]. He's made a promise to himself, and he's sticking to it: "Si te juré nunca volver debes creerme / Que cumpliré y mi promesa es no volver" [If I swore to you I'd never come back, you must believe me / That I will fulfill it and my promise is not to return].
He's pretty blunt, actually, telling his ex that "En este mundo nadie es indispensable / Tú puedes ser feliz sin mí y yo sin ti" [In this world, no one is indispensable / You can be happy without me and I without you]. Even though she might be saying she can't live without him, he remembers the pain she caused. He says, "Sufrí bastante que juré nunca volver" [I suffered so much that I swore never to return]. So, when she asks him to come back now, his answer is firm: "Jure que nunca volveré y no volveré" [I swore I'd never return, and I won't return]. It's a song about pride, pain, and sticking to your word, even when it's hard.
