Lastimas comes from the verb lastimar, meaning "to hurt" or "to harm". It's a direct and emotionally charged word that cuts to the core of the song's theme.
In the lyrics, the singer repeatedly asks, "¿Por qué me lastimas de estas formas?" (Why do you hurt me in these ways?). This word perfectly encapsulates the pain and confusion of being in a toxic relationship, making it a compelling reason to explore the song's narrative.
Have you ever been in a relationship where someone keeps saying they love you, but their actions tell a completely different story? That's exactly what Antonio Hernandez is singing about in "Déjame Ir" [Let Me Go]. He's fed up with his ex constantly claiming to love him, even saying things like "quedarías tu vida por mí" [you'd give your life for me], while simultaneously hurting him.
He's reached his breaking point, declaring, "ya me cansé contigo No me vuelvas a llamar No quiero saber nada de ti por favor ríndete ya" [I'm tired of you. Don't call me again. I don't want to know anything about you, please give up now]. It's a blunt and powerful message to someone who just won't take no for an answer, especially when they keep suggesting casual meet-ups. He's making it clear that there's no going back, even if they've erased him from their heart, he's already eliminated them from his. He's done, and he wants them to understand that he's not coming back.
