I give you credit for trying to stay level headed about this last turn of events. I also know you are hoping this is a good sign. Bear in mind that she pretty much got dumped by OM and her ego is hurting badly. She knows if she turns to good ole Kramer, he will tell her how wonderful she really is, and he will want her even if OM doesn't. In so many words, you told her what she wanted to hear......even saying you would not describe her in the words OM used.
All in all, you didn't screw up too badly. You need to play it really cool right now, or she'll hurt you again. She was looking for an ego shot and you gave her one. Your biggest problem at the moment is not allowing yourself to start blowing this out of proportion and believing she's ready to reconcile. Instead of assuring her, it would be better (if she does this again) to just listen and if she seems to be pushing you, tell her you need time to think about things.
If you start acting excited/happy, she'll pull away. If you start pursuing, she's gone. Don't make it too easy for her, b/c she has to work to get you back again. Otherwise, you will go through this again, IMO.
I have to go for now, but I saw where you thought detaching was similar to
Really GAL big time, now. Do not try getting closer, or any of that stuff. She was reacting out of her emotions. If she meant what she said about being sorry, time will prove it. Her words have been said by many insincere WW's. Yes, she's made a mess of things, but how remorseful is she for the pain she's caused you and the destruction around her (including the M).
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
