This song maybe talks about new love beginning while, let's say, "old" love is still there and so the bittersweet feeling that this was not what it was supposed to be - but maybe what love is. And this seems to carry the ambiguities of a wanted love in a unwanted and socialy condenable manner. The ambiguities of wanting to be with someone and not wanting to feel bad/wrong about it.
