My W and I had discussed the OM for about a month off and on. She seemed ashamed at first and then started getting angry with all the questions I would ask weeks later. My MC said I should start trusting her again if I want this to work.
Currently there are no signs of her having an A, at least a physical one. She's home everynight and she calls me more often when we aren't together. I'm just not sure anymore, and I'd hate to let my guard down.
Yeah, questioning her all the time is no good -- it sets you up as the "traffic cop," and that's not very attractive, and not conducive to reconciliation. That's why transparency is so important -- it's the TRANSPARENCY SYSTEM that is the "cop", not the betrayed spouse.
I disagree with your MC -- trust has to be RE-EARNED once there is infidelity. To blindly trust is simply naive. Does this MC have any experience working with infidelity and successfully healing marriages harmed by it???
