I guess I wonder bc the X has been nice on the phone is this a positive step? Is this movement in the right direction? Will she return to only revert back to her behavior? Was she being nice bc she is attempting to manipulate me into keeping my D on her terms? Any thoughts?
Who knows. And it doesn't matter.
Not trying to be flippant. But, whatever is motivating her or going through her head b/c you are working on you for YOU. You do thinkgs b/c they are the right thing to do for YOU.
She might come back, might not. And, in the end, that's not the goal. The goal is to get you right, b/c YOU need that (and so does your D) and, it is the only chance of luring X back.
Don;t waste your energy trying to figure X out. You won't be able to and, it will just frustrate you.
