"That might be your opinion, but it absolutely isn't the opinion of the vast vast majority of counsellors, and all those who have written books."
Really? They say that if the person who cheated won't come clean (to your satisfaction - I believe the OP when she says that she did, esp as he had the phone details and would quiz her repeatedly to make sure that what she said always matched - sounds like he had the info), that you should abuse them to get it?
Surely if you don't feel your cheating partner is holding up their end of the deal, you leave instead of abusing them. Choosing to stay and to punish them indefinitely is wrong.
No, hence that's not the part of your post that I quoted

Did you not read my post properly?
The experts say that there needs to be full truth on the affair. Ideally not the blow by blow sexual details, for the sake of the betrayed, but that rebuilding requires full truth. When it started, how it started, how they communicated, how often, when they met etc
Sunlight is the best bleach, and all the cosy little secrets of the affair need to be in broad daylight, because part of the appeal of the affair is the secrecy it lives within. As long as there is secrecy and private details, the affair exists as a special little thing between them.
To rebuild the relationships requires the destruction of the affair, so no contact, no secrets
So by signing up to rebuild, the OP does not retain the right to carry on lying or withholding information
So it might be your opinion that it was her right to do so, but that belief is not shared by any actual expert on the topic.
The point at which the OP carried on gaslighting and lying, she was committing extreme emotional abuse to her partner. It therefore doesn't come as any surprise that he was traumatised enough to start questioning her at a time of day that he knew she would answer questions.
Presumably if she didn't like this continued questioning, she would have been able to put an immediate stop to it by coming clean with the details he needed to hear.
She didn't, so carried on the emotional abuse of her husband.
Obviously two wrongs don't make a right here, but it's very hard to see why you're calling out his behaviour as abusive, and defending to death her right to abuse him
