Cover art for Breaking It Up lyrics by Lykke Li

I think it's about being in a relationship for the sake of it where you don't feel the same way about the person and realising it's better to be alone than with someone you're not that bothered about. I can see the waiting for someone and deciding not to so any more theory, however the line 'I let you think that I'm yours when I'm not' contradicts that I think.
