You are entitled and encouraged to FEEL the whole deep, wide, ugly, screaming rage at these people and to THINK dark vengeful thoughts for the deep hurt inflicted on you.
You should also EXPRESS these dark thoughts and excruciating feelings in a safe way with a v trusted friend, therapist, via a journal, punching a pillow, screaming on your own in the woods, snotty sobbing in your car etc.
All of those are safe constructive emotional processing techniques. These will allow you to get it all out and importantly then create little spaces each time inside you for your healing. Then when the next phase of anger subsides look to proactively build in emotionally nourishing, calming self care activities with radiant people who leave you feeling cherished, valued and whole.
There is NOTHING to be gained by talking to the OW or your OH - and EVERYTHING to loose - your dignity, self respect, your emotional stability etc.
You will not find the closure and healing that you are after with the persecutors of your pain.
You will find more shame and humiliation - and you will have to then take responsibility for seeking it out.
Know that it is healthy to feel so deeply, to think so darkly and to express so rawly - but only in a safe place.
When someone throws a grenade at you like this, the eyes of the world are trained on you, the victim, to see what you do next. They are not looking at the perpetrator of the assault.
The moment you retaliate you are now not the victim but an equal participant in a fight.
Keeping your dignity, straightening your crown and moving on regally (in public at least) is incredibly powerful and empowering.
I hope that you can resist the waves of emotional urges, impulses and compulsions to let rip - know that it is healthy to feel and think like this (for a time) but it is not emotionally healthy, intelligent or dignified to act these thoughts or feelings out.
Today you have total power in your silence and detachment. YOU will hand over all of your power the moment you make a connection. You will have lost.
You are aiming for a place of indifference - this is a calm peaceful place like an oasis in the desert - it’s a long way away and requires you to put one foot in front of the other each day and care for yourself gently. You need to keep you eyes on this prize and not be drawn off track and wasting your finite and precious resources on something else - otherwise you will never get there.
Sorry you are enduring this and wishing you to a more peaceful place.
