To me this song is about Karen letting someone go that is very close to her.
"I know what I know
I know on car ride down
I hear it my head real low"
She has done something wrong(cheated on him) or has been lying to him and knows she isn't good for him. She is going to see him to break it off and can't stop thinking about it.
"Turn into the only thing I ever, Turn into hope I do, Turn into you"
She still loves him and wishes she could be as loyal and perfect as him. She doesn't want to give him up but knows it is best for both of them.
"Well I know that girl you found, Keep that kind of window closed"
She's trying to explain to him that she isn't the perfect girl he sees her as (love can make you see what you want to sometimes).
"Can't say why I kept this from you, My those quiet eyes become ya"
She should have told him right away and he is kind of sitting their not wanting to believe what she is telling him.
"Leave it where it can't remind us, Turn this all around behind us"
She is still fighting to let him go, she wishes she could change/forget the past.
"Oh... Well I know, How far I am to keep you out, I'd like to tell you all about it"
She has to stay away from him for his own good or she will hurt him more, but again, is fighting against what she knows is best for him.
"I know this last time round, I'll hear it in my head real low"
This is the end for them, but she will always remember him.
"Turn into the only thing that ever known, Only thing that ever knows..."
