Personally, I think this song is about liking/loving someone who the singer doesn't really WANT to love. ("Now I am tired and now I am bored") ("It wears me out again") Like, she goes around and around in circles, liking this person, keeping them held on a string or leash, and yet she doesn't love them anymore. ("But I had it once, but not anymore") She wants to have her cake and eat it too.
