So if she starts acting nice and says she'll give up contact with OM and go transparent, then how to proceed? Do I still detach and GAL? If so, for how long?
Then you pause and say either "I'm afraid it's not that simple anymore," or "Hmmm. I'm not sure how I feel about that. I'll have to think about that; a lot has changed."
That may all still be premature, but you have to guard against faux remorse. Are you going for compliance, or commitment?
