It is surprising the things that can trigger a slip: A memory that brings the pain back with it, a comment from a none-too-helpful friend, an action or situation that brings doubt about the wisdom of having forgiven. But each time around it gets easier: I move through the process faster, until at last I can more closely mirror God's forgiveness of me and "no longer remember".
Then one day something happens that brings the event to mind and I find I truly have let got of the hurt, truly welcome the person more wholly back into my life, trust and value them as I long to be trusted and valued when I mess up.
Please don't mistake a slip with proof that it was all pointless. Get up. Dust off your backside. And start back through the process which will get easier with each iteration.
And the freedom, the release, the joy is worth all the work. What a blessing to leave the baggage on the side of the road and travel lighter, faster on the journey to becoming the person we were created to be, fulfilling our purpose without the distraction and doubts.
