Well, let's be fair, it's always an option. We always have an option to walk away at any time, that's the way it works.
W is going from "we are done/over/finished" blame rage last week to very warm, communicative, and wanting to spend time together this week. She even kicked around the idea of us opening up a fitness franchise together yesterday. I have no idea how to read any of this, and if I ask, it becomes R talk which usually sets things flailing in the wrong direction.
I'm not sure a conversation with an L will offer clarity or will be a waste of time.
