Esconder translates to 'to hide' or 'to conceal'. It is an emotionally charged verb often used in Spanish songs to describe keeping a heavy secret, like a forbidden romance or suppressed feelings.
In this dramatic track, Enrique confesses to an infidelity, singing "Difícil esconder / Lo que me hace sentir" (It's hard to hide / what she makes me feel) to admit that his new romance is too powerful to keep hidden.
This song is one of the most direct breakup confessions you'll ever hear. Enrique Iglesias isn't just ending a relationship; he's explaining exactly why, and it's a bombshell. He starts by telling his partner, "Hay una cosa / Que te tengo que decir" (There's something I have to tell you), and then drops the truth: "Mientras estabas lejos / Otra estuvo aquí" (While you were away, another woman was here). He claims it all happened so fast he didn't even realize, but then admits he fell for this new person and can't lie about it, saying, "La quiero demasiado" (I love her too much).
Instead of asking for forgiveness, he simply asks his partner not to cry for him. The chorus is a plea for an easy exit: "No llores por mí / Deja que me vaya / Sin verte sufrir" (Don't cry for me / Let me go / Without seeing you suffer). He offers the classic, slightly cold comfort that she'll find someone else to make her happy. It's a song about someone who has already made their choice and is just delivering the bad news before walking away.
