To Have Loved and Lost

"Love given or love taken is never lost. Once you've loved someone, the love is always there, even after they're gone."
~Dean Koontz

Sometimes love isn't enough to sustain a relationship. The relationship ends but the love doesn't. It's still there in your heart but the joy it brought you before now only fills you with pain, as that person is no longer there to complete that bond.

How do we rechannel that intense emotion into something more productive? How do we survive when love doesn't let us forget?
