I Heard You Crying in Your Sleep

I know you tried your best to love me
You smiled when your heart told you to weep
You tried to pretend that you were happy
But last night I heard you crying in your sleep

You gave the best years of your life dear
And each precious vow you tried to keep
I love you so much I want you happy
But last night I heard you crying in your sleep

Your heart is yearning for an old love
With new love it's useless to compete
It hurts me to know you are unhappy
But last night I heard you crying in your sleep

You know that you are free to go dear
And don't mind me if I start to weep
I know I can never make you happy
'Cause last night I heard you crying in your sleep
