You make valid points. But the onus is on the man to tell his wife. A mistress does not know the inner workings of a marriage or family, she does not have a clean unbiased slate to make a decision from. And she cares not for the health of the wife or the welfare of the children but of her self, her sense of justice, and most likely the possibility that she can have the man all to herself. Her motives are not only not pure but she indeed has motive to lie. You may think you want to know, you may even want to know. But the mistress is not the one to make that call in a marriage. Ever. It is on the man to decide if the adultery needs to be confessed, or not. He is the one in the marriage, he is the one who is one with the wife, and he is the one ultimately charged with the welfare of his family. Not the woman on the side. The woman on the side cares nothing for the wife or the kids, she cares only about her own guilt, and perhaps getting the man. Disguising this as an altruistic decision to “tell” the other woman is not the right way to go about it. What she needs to do is STOP immediately, go to confession, and move on. If she wants to do anything beyond that, she can tell the man to do the same and to go back to his wife.
She does need to stop this and go to confession and move on.
But I believe she has a duty to tell the wife as well.
IMHO, the husband who is committing adultery is absolutely NOT thinking about his wife, any subsequent children and the general welfare of his family.
He is just as likely to lie to his wife as the mistress is. He is probably more likely to lie then the mistress because he has plenty more to lose.
The husband clearly cares nothing for the wife. Nothing more then the mistress. He cares about his own needs and gains and not for his wife. Anyone who commits adultery by bringing another person into the marriage, clearly does not have the best interest of his wife/husband and is NOT fulfilling his/her role within the marriage.
The husband is not protecting the wife or his children.
Why not have the mistress tell the wife?
Clearly, she could be, and probably is, doing this for selfish reasons but at least she’s putting the power back into the wife’s hands.
The wife can then decide if she wants to reconcile. She can take back control within her marriage and put a stop to this nonsense.
She could stop intimacy and demand that he get checked for any diseases, for her own protection.
She could open her own bank account and set aside paychecks and savings that can no longer be spent on gifts, hotel rooms, dinners and other things for his mistress.
She could speak to a lawyer and at least find out what her rights are, should she chose to proceed with divorce.
She could demand No Contact and complete transparency with phones, computers, emails, bank accounts and so on, just so she is at peace and trust can be rebuilt.
They could go to counseling both individual and marriage and try to fix this brokeness.
There would be very real consequences if the husband is outed.
At least the wife could make the decision on her own.
The mistress wouldn’t have a say within the marriage if she reveals it or not. She can’t decide for them if they reconcile or divorce. If they do divorce, the chances of success within their own “relationship” has very little, to no chance, of succedding anyway since trust was never their to begin with.
All the mistress would be doing is giving the wife a head’s up and letting her know vital information that could save her marriage or at least save herself from more damage and destruction.
