Hi Jim your state of mind appears to reflect my own at the moment although my W is nowhere up to speed with your's! Since June I have not felt a need to check, not because the trust is back, but because, despite the A still existing (and I am of course powerless with this workplace sitch), I do seem to have "healed" somewhat. I so sometimes wonder if I still "care" in that respect? In recent days her cell provider has announced that their online facility for checking texts will be removed at the end of November and also my W has suddenly changed her phone password. Previous to the summer that would caused panic as I would not have been able to "keep tabs on the situation". But not now.
The way it sounds with your sitch I think these tentative steps may well reap rewards but like you intimated it will never be the same again (that might not matter of course!). In my sitch I just have to decide in the end whether I wish to go on for another potentially 40 years with a person who might stray again at some point in the future if we can't get all these things out in the open.
