Aferraste comes from the verb aferrarse, which means to cling, to hold on tightly, or to insist stubbornly on something. It's a strong verb that conveys a sense of stubbornness or refusal to let go.
In the song, the lyric "Pero te aferraste y se terminó" (But you held on tight/insisted and it ended) refers to the ex-partner's stubbornness or insistence on a certain path, which ultimately led to the end of the relationship. It's an interesting word because it implies a deliberate, unyielding action that had significant consequences.
Ulices Chaidez brings us a song about moving on after a breakup, even when your ex comes crawling back! The singer starts by reminding his ex that he begged them, "Un millón de veces yo te supliqué / Que no te marcharas, que aquí estabas bien" [A million times I begged you / Not to leave, that you were fine here]. He did everything to save the relationship, but they were stubborn and it ended, leaving his world shattered.
But here's the twist: the ex thought they were winning by leaving, assuming the singer would be lost without them. Now, they're lonely and regretful, calling him up. And his response? A blunt, "A mí qué me importa que te duela tanto" [What do I care that it hurts you so much?]. He's over it! He reminds them that they broke their promise to stay by his side, and he cried his tears alone. He makes it clear that their current pain means nothing to him, because "a ti mi dolor / No te importó" [my pain didn't matter to you]. It's a powerful message of self-respect and not letting someone back in who didn't value you the first time around.
