Also, you were not at the point yet to establish "better" communication. IMO it was more about establishing "civil and normal" communication. Nothing can be built on moans and grunts. That wasn't to improve anything. It was to hear words when you have a conversation which is the very basis of a conversation!
Your W doesn't respect you. She calls it governing what she says. I call it asking to be treated w/the same courtesy you would treat a store clerk. She doesn't respect you so she doesn't treat you w/common courtesy.
DB all over and this time GAL for you and limit the time you spend with her. She has told you to have no hope so proceed on with your own life.
