Well, the song seems to be a story about a friend whose falling for his best friend, in the beginning he speaks of crossing “boundaries”. In the second section, he begins to explain what it is he wants from her, and that if she’s willing to be with him he’s ready because he’s already falling for her. In the third to last section he’s telling her that he has never doubted her loyalty to him as friends, and that she’s always been there for him and as a result of her loyalty, he has always loved her because of it. He than begins to ask for reassurance because he’s sure that what they have is special, in the chorus of the song he than tells her that if she’s willing to be with him he’s willing to be with her, and that he’s been falling for her. At the very last part he reassurance his love for her and the fact that he will always be there for her and that he will always come back even if it may not work. That’s just my interpretation of it :).
