Summary - wife already filed for divorce, I am attempting a last resort. I admittedly have doubts about some of what I am doing. Particularly, how little communication there is. I had felt she was possibly softening before going more restrictive with my communication, and after nearly a week and a half, things definitely seem to have regressed IMO.
For me, initiating conversations (not relationship related) was more of a 180 as I have typically been more quiet and reserved, so a lot of this "detachment" to me, feels like doing more of the same.
