Now or Never

So you try to tell me
things are going to change.
But do you mean it?

Can you really say
I'm going to stay the same?
I can't wait for you
forever.

It's not as if
you left me
and took my heart with you.
It's not as if
I can love you
after all you've put me through.

So how can you say
you'll always love me?
And we'll always have a chance?
I keep asking myself
if it's right
to leave while I can.
