I agree with the others. You did a good job in a very difficult situation. A situation that is showing your W's insecurities She has to attack you because she doesn't feel in control and/or questions her own parenting abilities. Remember, anger is a secondary emotion and means she is still dealing with her own internal issues so don't take it personal(easier said than done, I understand). Keep going on this path and let her be angry, just don't get sucked into it.
Time to start a new thread.
Accept what is, let go of what was, and have faith in what will be
