I'm pretty sure that this song is about not knowing exactly what you want in a relationship. The girl in this song is unsure about the relationship and hence "wanders", which is probably a reference to her trying out other men and such. This song is basically the narrator saying that he's been patient for long enough and can no longer stand by idly and wait for her to make up her mind, because she's probably fairly capricious.
