To me, this song is about one person who uses another person. The narrator is being used. He's always been trying to keep the "love alive". But the girl is always messing around and taking advantage of him. He's threatening to leave her:
"I won't be around for you to step on me
If you want me to stay you'd better stop pushing me around"
And she never proves to him that she really loves him:
"Then you say that you love me.
How can I believe you when you shove me away?"
