The good thing about this flight syndrome is that you can probably lock in a deal where she gets almost nothing in the seperation agreement. That's a thin silver lining on a big, nasty dark cloud.
I agree. You may be able to put a "sweetheart deal" (for you) in front of her in her current state, as a cheater in this frame of mind will often do ANYTHING just to get themselves out of contact with their betrayed spouse. She may also be getting pressure from OM.
