'm tired too. [ She sighs the words out, feeling increasingly miserable and dizzy.] I know 'm not a great girlfriend. [ Her eyes close. ] I don't want to date other people... I want to be mutua-mutual-mutually [ She struggles with the word because realizing that isn't the right word at all.]No, no. I want to be exclusive. But I don't like feeling like someone's mistress or somethin' dirty or wrong. I mean my dad would totally kill me if he knew but here it never seemed to matter. [ She rambles and sighs.]

But I know it matters to you and like, I really, really like you. Like totally like you. I dunno what to do. [ And that's the crux of it, the reason she's been acting so... well, uptight.

She likes him more than just "like", she doesn't want to fool around with other people now and the idea of that is scary. So she pushes, prods and tries to get him to commit. Because the whole dirty little secret part of this has stopped being hot and now, she just wants him and wants to love him.]
