Seja Ex is a lively Sertanejo track where Brazilian duo Henrique & Juliano tackle the messy limbo that can follow a breakup. Over an upbeat melody made for singing out loud, the narrator speaks straight to a former lover who keeps walking in and out of his life. He begs her to make up her mind: if she left to become an ex, she should act like one—go out, kiss someone else, disappear, anything that stops her from hovering over his every move.
The lyrics mix humor and frustration as the singer admits this half-relationship is “braking” his life. They are both past thirty, no longer kids, so the time for indecision has passed. By repeating the command “seja ex” (be an ex), the song turns personal heartache into an anthem about setting boundaries, growing up, and protecting your own peace when someone you love will not commit to staying or leaving.
