Acostumbré comes from the verb acostumbrarse, meaning "to get used to" or "to become accustomed to." It's a key word in understanding the emotional core of this song.
In "Y Ahora Qué?", the singer expresses a deep sense of resignation and habit. They sing, "me acostumbré a esta vida, a esta clase de amor" (I got used to this life, to this kind of love). This reveals a poignant struggle where the love might be imperfect or even painful, but it has become a familiar, almost inescapable part of their existence.
Pimpinela's "Y Ahora Qué?" [And Now What?] is a really relatable song about being stuck in a relationship that isn't quite working, but you just can't bring yourself to leave. The singer is feeling the years slip by, saying, "se me pasan los años sin poder ser feliz" [the years pass me by without being able to be happy]. It's that feeling of waiting for someone to make up their mind, even when you know it might not lead to happiness.
She's tired of the lies and the waiting, asking, "qué quieres que te mienta, que invente lo que aún no siento?" [what do you want me to lie to you, to invent what I don't feel yet?]. It's a blunt question, showing her frustration. She admits, "lo único que sé es que dejarte no puedo" [the only thing I know is that I can't leave you], because she's just so used to this kind of love. It’s a powerful look at how comfort can sometimes keep us from making necessary changes, even when we know we should.
