For she lies, laughing low with love; she lies And turns his kisses on her lips to sighs, To sighing sound of lips unsatisfied, And the sweet tears are tender with her eyes. "Poems & Ballads (First Series)" by Algernon Charles Swinburne

Can you commit your ways to him and feel that if desire is still unsatisfied, if obstacles are not yet removed, if trials yet bear upon you, the Father- love is not growing cold, nor his hearing dull, nor has he forgotten? "Heart Talks" by Charles Wesley Naylor

In fact, morbid anxiety means surely unsatisfied love. "The Dream Doctor" by Arthur B. Reeve
