I myself am dealing with some NPD (Narcissism) issues with my own wife, so I completely understand.
Since I've confronted W on the A, do you believe there is any point in discussing it further or should I just let it sit now and do the LRT/GAL?
Reality has entered the picture, and as the legal issue becomes more defined I would anticipate some sort of disruption by MIL/BIL of the A in order to attempt to placate me if/when I gain the upper hand in custody, or at the very least the illicit nature of the relationship will invite too much stress on W/OM and it will collapse.
Right now I am just enforcing strict boundaries (contact once per day via text message about D1, optional phone call 5-10 minutes on Friday to discuss D1, and pickup/dropoff on Saturday) and focusing on GAL activities.
I have no desire to confront OM, and I liked the example you gave in another thread about it being like the President refusing to deal with Terrorist leaders.
Basically W asked for the D, I have seized control of the proceedings, and now it is just a waiting game as her attorney works to salvage the situation. I'm pretty sure my exposure/etc. short-circuited W's BPD distortion campaign as well.
I'm not blinking.
