(Last Night) 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
 Last night, I heard you crying in your sleep
 Your heart is yearning for an old love
 When you 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
