Puppy, you mentioned that she should propose a solution. Does she really need to explain her "plan" or can she just carry it out?
That would depend entirely on how safe YOU would feel in not having an explanation of what it is she's put in place. The whole point of a transparency plan is for the betrayed spouse to feel safe again in the relationship. It's the old "trust, but verify" thing. Unless it's something that you can verify from time to time, I can see where all of your old doubts and fears would start creeping up again, no??
