Just an update. I told the W I need an additional 90 days and she was understanding and agreed. Perhaps it was my imagination, but she almost seemed relieved. I still don't think she is having second thoughts about the divorce though.
She is moving out in two weeks. Now that some of the tension is gone, should I start spending a bit more time with her or should I continue to distance? I will of course continue with the 180's (which are no longer for her, but for me!)
