Wonderfully writen. I think Donna's fate is something that bothers us all so it's nice to see Rose take up our arguments with the Doctor and come to the same conclusions we have (though I know it took me a while to forgive the Doctor). In the end I think the Doctor did the only thing he could do. Rose is right, Donna would have wanted to remember, regardless of the cost but the Doctor knows that she can be fabulous again without him. Maybe even after everything she's been through and learned about herself, the Doctor still believes in her more than she does herself.
