Desamor is a powerful word that literally translates to 'un-love' or 'lack of love', but it's often used to mean 'heartbreak' or 'falling out of love'. It's formed by adding the prefix des-, which negates the word, to amor (love).
In this iconic bachata, the singer tells Cupid he's done with romance. He feels he has received "la fortuna del desamor" (the fortune of heartbreak) as an inheritance, a beautifully ironic line expressing his constant bad luck in love.
Have you ever been so done with romance that you want to send a message to Cupid himself? That's exactly what Aventura does in this classic bachata track. The singer is fed up. He directly tells Cupid he's a failure, complaining that from all the flowers he's given away, "en mi jardín no hay ni una flor" (in my garden there isn't a single flower left). His solution is hilarious and blunt: he wants Cupid to act as his messenger and tell Love to get lost.
The message is simple: "dile al amor que no toque mi puerta / Que yo no estoy en casa" (tell love not to knock on my door / That I'm not home). He says his heart has been let down too many times, so he's officially checked out. He's even put his feelings on a diet, "Tengo a dieta los sentimientos" (I have my feelings on a diet), to avoid any more disappointment. It's a dramatic, funny, and very relatable way to say you're taking a break from the dating world.
