Well done you looked in a book about what it all means. CONGRATULATIONS.
That’s not what it means. It’s about someone who’s only with someone for their money “She hides true love en su bosilo" en su bosilo means in your pocket in Spanish (you keep your money in your pocket - the money is what she’s really in love with)
The 3 different names mentioned is about her not being sure if his name is Alejandro, Fernando or Roberto, because they’re so similar and she doesn’t really care about him.
But she doesn’t want to “be with (him) like this anymore”, so she’s basically saying in the song it’s over and that she’s “not (his) babe”.
She’s not using him because she’s a bad person she’s just young (“she’s not broken, she’s just a baby”), doesn’t understand what she’s doing and has had a lot of bad relationships (“now he’s gotta firefight gotta cool the bad”). She enjoys being treated so nicely (“her boyfriends like a dad" - A dad cares about it’s child a lot) because she’s had bad relationships.
I also know what Dance in the Dark, Speechless, Telephone and Bad Romance are really about :’)
