Engañaste comes from the verb engañar, which means to deceive, trick, or cheat. It's a strong word that immediately conveys betrayal and heartbreak.
In
Agua Marina's "Porque me engañaste" is a really direct song about feeling betrayed in love. The singer is completely bewildered, asking, "¿Por qué me engañaste?" [Why did you deceive me?]. They gave their all, saying, "me entregué todo por ti" [I gave my all for you], and now they're left wondering why their partner is pulling away without explanation.
It's clear the singer is hurting deeply, describing themselves as "sufriendo como un niño" [suffering like a child] because of this lost love. They believed in a "amistad sincera" [sincere friendship] and a true connection, but it seems their trust was broken. It's a raw expression of confusion and pain after giving everything to someone who then walked away.
