“To love, to be beloved again, and know
A gulf between us:—aye, 'tis misery!
This agony of passion, this wild faith,
Whose constancy is fruitless, yet is kept
Inviolate:—to feel that all life's hope,
And light, and treasure, clings to one from whom
Our wayward doom divides us. Better far
To weep o'er treachery or broken vows,—
For time may teach their worthlessness:—or pine
With unrequited love;—there is a pride
In the fond sacrifice—the cheek may lose
Its summer crimson; but at least the rose
Has withered secretly—at least, the heart
That has been victim to its tenderness,
Has sighed unechoed by some one as true,
As wretched as itself.”
