Regarding Regret lyrics

Take a closer look at what may be
Your only enemy
Has been the way you waste your life away
It doesn't have to be this way
You can break the circle...this time around
Why can't I be the one to ease your pain?
And you're so far away
And I'm here searching for a better way
Constant reminders of our yesterdays
Are all that help me look towards better days
Leaving was the hardest thing I've ever done
So many moments wishing I had never gone
Sometimes hanging on is harder than letting go could ever be
At least that's how it seems to me
And how could you go back again...back to all the pain again?
So hard to watch, but I can't turn away
It's tearing us apart again
Destroying what we've built again
And I'm still trying to understand
Is this the way things have to be?

All I wanted...was to help you through this
Never asked for...anything in return
Just don't forget me
Just don't forget me
Just don't forget me
'Cause I'll be waiting here for you
