Reprocharte comes from the verb reprochar, meaning 'to reproach' or 'to blame'. It's a strong verb that conveys a sense of accusation or expressing disapproval.
In the song, the singer states, "Yo no quiero reprocharte tu silencio ni tu olvido" (I don't want to reproach you for your silence or your forgetfulness). This word sets a poignant tone, indicating a past hurt but a present desire to move beyond blame and simply reconnect.
This is a cumbia-style plea from someone who just wants the person they lost back, no questions asked. The singer opens by refusing to play the blame game: "Yo no quiero reprocharte tu silencio ni tu olvido" (I don't want to reproach you for your silence or for forgetting me). He won't even remind her that he loves her for real.
Then comes the generous part. "No me digas lo que has hecho, ni me digas dónde has ido" (Don't tell me what you've done, or where you've gone). He doesn't want the story. He only wants to look at her and forget how lonely he's been.
The chorus is wonderfully simple: "Volver a verte" (to see you again), to know she is real, to look into her eyes and "besar tu frente" (kiss your forehead). A kiss on the forehead is tender, almost protective, not a big dramatic move. And he ends with "y nada más" (and nothing more), which is the whole point: that alone would be enough.
Great song for practising volver a + infinitive (to do something again) and the negative commands no me digas (don't tell me).
