So I dropped the ball tonight big style. I had it all in my mind about distance and the 180s etc. And out of the blue she said "I can't carry on like this with this atmosphere any more" I then said to her that I cannot control how she feels and that she has decide and tell me what she wants. She then said that I am looking at her like shes a piece of [censored], I should have walked away, but I then explained how I can only control what I can do, not what she wants to do. She then said I've got colder, we then bavk and forthed- no shouting or anger from me, just calm focus on repeating the message. I also said that while she continues to show no fight for the marriage I didn't understand how she wants me to communicate with her. I did set one boundary and that is that I will not allow our failing R to begin to impact the children, so no conversation in front of the children and absolutely no criticising or belittling and the constant snide remarks. She is carrying so much resentment it is defo not displaying any emotion toward me
Aaarrgghh
