To clarify, when I said "yes, she does [need to do it your way]" that's keeping in mind that she supposedly wants reconciliation, and that Theevent's "way" is her taking accountability for her own choices and doing the internal work on herself to fix that which allowed her poor choices.
It's easy enough to cheat and afterwards say that you'll never do it again. A WS might even genuinely believe they won't ever do it again as they promise it to their BP and/or to themselves. I know as a repeat offender myself, I've certainly been there, and my most recent incidents are 5 whole years apart. It doesn't matter what she says about whether she'll "resort" to infidelity again when the marriage gets bad, because the only answer that's compatible with reconciliation is "No," AND that "No" has to come with "And here's what I'm doing to ensure I don't do it again."
Because without doing that internal work, what is there to stop a WS from committing infidelity again when the same circumstances from the first time prevent themselves? Making boundaries like, "I'll distance myself from anyone I start feeling too interested in" is one thing, and it's easy enough to do, but it doesn't address 1) why you're developing interest in other people in the first place, and 2) how you're going to hold yourself to that boundary in the pits of temptation and marital troubles. Wasn't that what the WS was supposed to do the first time, and failed to do? Something fundamental has to change for Theevent's WW to become a safe partner. That's why she needs to do it "his" way.
With regard to the grey rocking... I'm not suggesting he avoid listening to her when she voices the marital troubles. He can say, "I hear your concerns, and we can work on those things after we recover from your infidelity," and that's both acknowledgment of them and a promise to work on them eventually, while re-centering the need to work through the betrayal first. I am suggesting that he goes stoney, calls a time out, and politely exits the conversation whenever she begins to blame shift, starts to argue with him, or does the thing where she needs everything to feel equal. Because Theevent is not to blame, that's not something he should accept or even entertain arguments over, and things are most definitely not equal, nor are they going to feel that way for a long time. The grey rocking is a tool for asserting his boundaries here, keeping things peaceable, and sending the message "This is what I need from you, and I'm not willing to accept less. The more you fight me about taking responsibility, the more likely it is I will need to detach further to be safe, and our reconciliation will eventually fail if it continues that way." It's not a threat, it's just a reality that she needs to understand. And saying it with words alone is not doing the trick.
Good insight on the abortion-related shame, Evio.
