You are correct, I have NOT yet talked to her about what it would take to reconcile... because she hasn't brought it up or done anything to indirectly reconcile (return to the bedroom, etc.)
I will follow everyone's advice. I will continue to detach, GAL, etc. if she directly discusses reconciliation or indirectly tries to reengage our M, I will have the talk (NC letter / transparency).
It's just an awkward time. I didn't expect her to end the EA without talk of reconciliation. I thought they would go hand and hand. This is a bit of a curve-ball.
