She sacrifice everything she had just to maintain the relationship but she get nothing back in return even when she broke up with her ex.
"It's unbelievable but I believed you
Unforgivable but I forgave you
Insane what love can do
That keeps me coming back to you
You're irreplaceable but I'll replace you
Now I'm standing on my own
Alone.."
And she has difficulties of getting over her ex.. =]
To me, this song is about after breakup.
