Jessi Colter - It's Not Easy lyrics

Your love grows colder day by day
We have reached the parting of the way
And I hope you never go through what I have been
Inside of me a fire is burning
I can’t stop my heart from yearning
It’s not easy, no not easy to forget
Can someone tell me just how long
The pain will stay before it’s gone
Will it end tonight or slowly fade away
Will it come back each time I see you
Heaven knows how much I need you
It’s not easy, no not easy to forget
