Lyric discussion by impossibilites 

I personally think that the overall theme of this song is miscommunication. Someone is being a bit two-faced, and says one thing one day but then the next says something and the other person has no idea what the relationship is about and so what they're saying is your actions are what is going to show me where your heart really is. And because of this lying or whatever it is, this double-conveyance, this person says they're "heart's not in it". This person is in love with the other but the other is not telling them properly, what their feelings are:

And impossible to really read When your talking with Two tongues in your mouth And I wish you'd quit this muttering Beneath your breath It's killing me You've not said nothing yet

Then the other starts to become involved in the relationship and wants to dig deeper but they're still sending mixed messages. Oh there's a lot to say but I think I've covered most.
