Here's the thing: if someone is in an ongoing, unrepentant affair, there are only a few types of conversations/communications they can have with their betrayed spouse, and ALL of them are cheeseless tunnels for the BS:
2) Seemingly POSITIVE ones. So long as they are still in contact with OM/OW and lying to their spouse about it, these are all "bullchit spin" at best, and outright GASLIGHTING and LIES at worse. And the problem is, the betrayed spouse inevitably sees this as "baby steps!" and true marital progress, when they are no such thing. They can lead to horrible strategic and tactical mistakes, esp. if the BS doesn't have a good intel system in place. Reading my old journal yesterday, I was BLOWN AWAY at how stable I was able to be in the face of my wife's deceit, simply because I HAD INTEL TO SHOW ME OTHERWISE. This can't be overemphasized.
3) LEGAL/FINANCIAL ones. These are best handled by your attorney, for the obvious reasons. If you start negotiating yourself, when you are way, way, WAY too emotionally entrenched in the situation (and also often running on too-little sleep and WAY too-little emotional needs of your own being met), YOU WILL MAKE FOOLISH MISTAKES and UNWISE CONCESSIONS.
4) FAMILY/LOGISTICAL ones. These are fine, but best handled via e-mail or text message. A cheating spouse will use these as a ploy to lure you into R convos and worse; SEE #1 ABOVE.
5) SMALL-TALK. This is fine, but only in RESPONSE -- don't initiate it if your strategy is to go "dim" and if it's to go "dark" you shouldn't even respond. If it's "dim," then only respond to one of every several communications, and usually delayed, because you're BUSY and GETTING A LIFE, remember?
