If you read the other books in the saga you would know that jacob is in them alot. This song is defidently in edwards pont ov view. Hes absualty in love wit bella. Hes trys to run frum it but he can't. He knows hes not sposed to need bella as much as he does but he can't stay away. He trys to avoid her but its to painful to live wit out her. In the second book, afta the whole thing wit that other vampire, he tells bella he wouldnt be able to live witout her. He trys to kill him self wen he thinks she dead. The song is saying the same thing. "i dont know wat i want, but i know its not you." edward doesn't want bella he needs her.
