Disclaimer: J.K. Rowling owns these characters; I do not.
She sometimes wonders if she's spoiled. She's got everything most people would hope for – a manor, a family that adores her, house-elves. And yet there's something important that's missing.
In her dreams, all the memories she had of Draco were revisited. Some people might think this was a nice way to remember him by, but for her it was agonizing. She didn't want to think about him for her own sake; it would surely drive her to run after him, leaving behind the comforts that she treasured. She knows that she treasures him more, of course, but she tries not to think about that.
Sometimes when she misses him to the point when she wants to die, she'll write a letter to him. She knows that he'll never see it, but it makes her think of what he'll say. She writes down how her younger sister stole her best gown and ruined it, and she can imagine him laughing.
She wants the war to be over. She wants to know where Draco is, and what will happen to him.
She lies down on her magnificent bed, staring about her room, taking in the glory of it all, and she knows that she'd trade it all to have Draco there right now.
