The Midnight Star question

So I just finished the book and when the end of the folktale said it was plainly a fake story told around the fire, I was like really? Is this some reverse psychology or something? I didn't know if Marie Lu was hoping we were smart enough to tell that it was actually real or that it wasn't but I'm obviously not. So I was wondering what anyone that read it and hopefully sees this post thinks. If Adelina and Magiano did go together,(hopefully) how did it happen? Was this his death and they finally were reunited, was it him finally reaching her somehow (like it said he was going to go towards her) and them being together again, was it an every night thing like Compasia and her lover, or what? Please comment your thoughts. I'm torn and don't feel like starting another book until my mind is at peace lol. :)
