Frances Anne Kemble - An Answer

Could I be sure that I should die
The moment you had ceased to love me,
I would not turn so fearfully
From those fond vows with which you move me.
Could I be sure, when passion's light
Had faded from your eyes away,
My own would close in endless night,
I would not shun their dangerous ray.
'Tis not your tenderness I dread,
But that affection's drear decay;
Would fate indulgent strike me dead
When its first glow of warmth was fled—
I'd live and love you till that day.
