Is there a song out there...?

So let's just make this simple. I've fallen in love with my
ex-boyfriend, but we're just friends. I'm pretty sure he doesn't feel
the same but I would do anything to make him mine. I really want a
song to listen to that is either close to my situation, or will make
me feel better.. lol

and if there's anything about him being a musician and his singing
would be awesome. lol

Thanks!
