"Not sure what I'm thinking at this point. Why do you want to do the marriage counseling?" -- and bounced it back to her.
Waywards spin from pro-OP stage, to "conflicted" stage, to pro-marriage stage, back to "conflicted," and all over that same map - -many times. It's the "plates spinning on the sticks" analogy that I reference often on the forum. I would say she's gone from "pro-OP" (or, at least, pro-D) stage back to "conflicted" stage, and this has upset her equilibrium.
It's important that you not (if you're like me!) RESCUE her from these conflicted feelings, or even move to MINIMIZE them. THEY'RE HEALTHY, and it's best that you don't "jump" too quickly, and instead push them back onto her again. Think of it like a tennis match -- "ball's back in your court, dear!"
