What does this song mean? It sounds like she wants her ex-boyfriend back.

When she says "Faith is not mine. If I could I'd unturn the hands of time" does it mean she cheated on him before? Or did they both cheat on eachother?

And I don't exacty mean when it says "Dancing in the Dark, Searching for a spark, of fire still burning." Can anyone help me?
