There's a strategy we touched on during the 'Blind Spots' navitents. It goes even further than what Ms. O'Brien suggested.
It's not easy, and maybe you're not ready yet.
The strategy is for you, and it allows you to move on without suffering anymore.
Wish 'em well.
Yep. Wish 'em well.
If you can bless the person who hurt you in a way that feels right to you, then you can clear the way to move on and for them to gain an opportunity to realize the hurt they've caused you and others.
It releases their power over you. You've let go.
You're free to move on even if the 'moving on' part is in your mind.
Your attitude becomes one of moving forward without guilt, regret or hardness.
Failure to move on only adds more harm. It steals your future as you focus more on your pain and less on your new opportunities.
The pain and bitterness then become your goal. The natural outcome of bitterness is to move backwards in increasing measures.
Take a moment if you're ready to do so, and wish the person well, doing so in a way that feels right to you. It can be very simple.
