Hmmm Cold is pretty much about a relationship where the guy loves the girl more than she loves him. The word "fly" could mean that she's ready to leave the relationship and he's basically saying that he doesn't want that, but if she goes, then she's going to regret it: "you will go without, the better part of me" also the whole notion of cold could suggest she doesn't really care too much about what she's doing to his emotional state and feelings.
