Her: Various stories of how I've hurt her in the past, the majority of which I can't remember...blah,blah,blah.
Me: "I'm eager to go to counseling to find out how we went of the tracks, but first, I need you to acknowledge that this has become more than just friends."
I like this response. It shows a combination of firmness and empathy. Your W is hurting, you'd like her to get to the heart of that pain, but not enable the wacky, out of control behavior that's covering the pain. That's compassion wiht a detached lens. That's where you want to be.
