You are granted a deal by a shady figure:
The horrible suffering your infidelity caused CAN be completely wiped out for both you and your BS - it would be as though they never found out the truth. All the teary-eyed questions would stop, all the blame and anger and "WHYs?!?" would cease immediately...
You were willing to knowingly allow your BS to be exactly as unfaithful to you as you were to them, AND you could never speak a word of it to them or anyone else. You could not berate, shame, or vilify them in any way. Your BS would carry on just as you did - believing they were getting away with it -and you'd have to watch it all unfold and never say a word about it.
PROS: you are spared for the rest of your life the pain of watching your BS grapple with your infidelity, and you never again have to sit in the "hot seat" getting grilled for answers you'd rather not give. Your BS is blissfully unaware of your infidelity forever.
CONS: you must watch THEM be unfaithful, but you cannot EVER confront them about it because
1) that's part of the deal;
2) it's only happening this way because you made the deal with the shady figure - your BS would most likely never have cheated if your own infidelity hadn't called the shady figure to make this deal;
3) you did the EXACT same thing and it would be hypocritical of you to utter one word of recrimination at or against them.
Could you accept those terms? Why or why not?
BSs, what do you think your WSs would choose?
