Let the past be past.

You will forget the shame of your youth. (Isaiah 54:4)

Two men...decided to take a shortcut...through a field where...cattle were grazing...[and then] forgot to shut the gate behind them. A few minutes later one of them...ran back to close the gate. As he did, he remembered the last words of an old friend...[to] his children...: "As you travel down life's pathway, remember to close the gates behind you."... Problems, difficult situations, heartbreaks, and failures were inevitable, but he wanted his children to know that they didn't have to allow those things to follow them through life.

This is especially true for believers. Once we were confessed a sin and have done what we can to right the wrong, we must put the incident behind us.
