Look at it this way...worst case scenario, she has "some" contact. It's possible that she does have triggers that set her back on occasion. You are being smart by giving her time to figure it out. If she "slips" she probably feels like an idiot...in fact I'd be sure of it.
What's in your favor is that this guy is a horse's ass. He can do nothing but disappoint her anyway! SO, even the worst case scenario will help you...as you become a better H, and this guy will slowly reveal himself to be who he really is...maybe some occasional contact will include some 2x4's.
The problem with that is, physiologically, even BAD contact is "contact," and re-stimulates the brain, and delays the onset of further withdrawal.

Yes. But trust me on this. Things will be said. Things she doesn't like. That will start turning that brain stimulation into something negative instead of positive.
And you overrate that stuff...IMO. Women's minds are more than the sum of their brain chemicals.
