Just pieces of a song I'm trying to write

[Cari Treadway]

So I'm just kind of sitting around watching Lord of the Rings: The Two Towers, listening to RJA. I'm a little inspired.
Well anyway, I was wondering what other people think of the lyrics I've pieced up so far, so I'm putting them up here in the hopes that someone will comment with some constructive criticism.
Remember, it's not a song, but pieces of one. So they don't neccessarily go together, or will end in this order. Or at all...
It's a song about heartache and lies, to put it simply.

"The false that has been laid inside your mind, it's just that
The thought that her unfaithfulness might actually have been

There in darkness will she linger
Forever bound unto her grief

You promised to love her forever

The cuts upon her arm are shallow
But the cuts on her heat are deep

Only in her dreams will she be free

How did you change
Turn out to be so cold
One word to break
All trust in her "

In the order they came out of my head in lol. What do you think?
