LOSE THE SPEW TOPICS. 90% of them are going to be "spin" at best and "b.s." at worst.
Focus instead on those earlier-in-the-marriage complaints she had, and those ones that YOU know to be true. The things that "sting."
You spend way too much listening to, responding to, and thinking about the SPEW. They call that stuff spew for a reason -- just put the spew jacket on and don't worry about it.
