Jodí is the past tense of the verb joder, which is a very common and versatile slang term in Spanish. While it can have strong, vulgar meanings, in this context, it's used to mean "I messed up" or "I screwed up."
Dalex uses this word to express regret and fear of karma, singing "Que como yo jodí, pues me jodan a mi" (Because of how I messed up, may they mess with me). It's an interesting word choice that adds a raw, confessional tone to the lyrics, making it memorable and impactful.
"Perder" is an apology. The narrator is asking someone to hear him out before she judges him for the person he used to be: always out, never serious, never paying attention to the details that matter in a relationship.
With her, he says, everything is different. He's scared of losing her because of what he did in the past, and scared that the way he hurt others might come back around on him. Still, he'd rather risk it and tell the truth than keep pretending, because he doesn't want to be without her.
The chorus is him handing her the decision: help me be strong, tell me if I'm enough for you, even if the answer means I lose.
