Initiating conversations IRT "us"? That may be possible. But conversations in general, not really. Between the kids. Despite being physically separated, I see her at least once a day 6 days a week, some days I see her 2 or 3 times.
The "going dark" has always bugged me because to me it feels like going silent is almost just a passive-aggressive reaction to her saying or doing something I didn't like.
Read Sandi's rules. No one suggested going dark. Nor going silent. Going dark means you don't respond, and no one said to ignore her. Not initiating means you avoid initiating any non-logistical discussions. IE, dealing with the kids is logistical. But keep it businesslike.
When she initiates you validate. Read the validation thread.
