My W is making unrealistic demand and I don't respond to them. She is trying to pick fights and I don't let her. She keeps reaching for those buttons to push and i am slapping her hands away... She can look but she can not touch.
^this what MrCAS said.
After filing divorce, W will text me all nasty and horrible and harping, and if I respond at ALL, I will respond with "I'm sorry you're upset." I figure the worst case she's learning the harsh lesson that divorce doesn't equal happiness.
