Again - you are assuming you know when you dont have a clue at all what your W is thinking or observing.

And if you really think about it from your W's POV do you REALLY think she wants to bring up what a hard time your kids are having when she is the one that initiated the D? I doubt it. So, it is good as a parent you brought up your observations and a potential action plan but the way you presented it was not good.

I see too much assuming on your part and it isnt your job to that or make sure your W is in the know. She probably is in the know and choose not to discuss it with you. Just because you dont think she is aware it doesnt mean she isnt. It simply means its a conversation she chooses not to have with you at this time.
