Conformarme is a reflexive verb that means "to settle for" or "to be content with". It combines the verb conformar (to conform) and the pronoun me (myself), creating a nuanced meaning of accepting a situation that is less than ideal.
In the song, Ozuna expresses his frustration at not being able to find his lost love. He sings "Pero se me hace tan difícil encontrarte, que tengo que conformarme" (But it's so hard for me to find you, that I have to settle), conveying that he must resign himself to just looking at her photo.
Ever been so heartbroken you just stare at a photo of your ex? That's exactly where Ozuna is in this song. He's completely fixated on a picture of a past love, singing, "Tengo tu foto pa volverme loco" [I have your photo to drive myself crazy]. He repeats this line over and over, showing just how stuck he is, thinking only of her with his "corazón roto" [broken heart]. It's a simple, powerful image of someone torturing themselves with memories after a breakup.
He seems to know it's his fault, mentioning he thought she would forgive him. Now, he's getting total silence: "Ni una llamada / Como si nada de nada" [Not one call / As if it was nothing at all]. He's trying everything to get her back, even sending letters and begging for a response. He makes big promises, trying to remind her of their life together, pleading, "déjate llevar de mí pa que veas cómo es que vivimos" [let yourself go with me so you can see how we live]. But in the end, he admits it's so hard to even find her that he just has to accept it.
