4) "Here with Me" by Michelle Branch
Every time Ron went on a date with Hermione, Harry felt like he died a little bit inside. Harry knew that he was being melodramatic but he just couldn't stand to be away from Ron, even for a moment. Harry knew that he had no claim to Ron's heart. After all Ron didn't know how Harry felt for him. But he couldn't help but feel betrayed. He knew that Ron had to go away, he knew that Ron loved Hermione and that in an inconstant world, Ron deserved every moment of happiness that he could find. Harry knew all of this but every time Ron left him, he couldn't help but wish that for once Ron would choose to stay.
