George Jones - (Last Night) I Heard You Crying in Your Sleep lyrics

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 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 if I start to weep I know I can never make you happy 'Cause last night I heard you crying in your sleep
