Stop trying to convince her of anything right now. Let the control go. Do what you know is right and continue showing her the love that she wanted to see before this all happened. She will see it but I guarantee she will NOT react to it. She will notice but you will get no validation for your efforts. Tough to hear and realize but your efforts will not go un-noticed. They are just being filed in her mind until she is ready to deal with it. Don't let the kids get involved. They already are. Your W is like mine the kids will get to her on their own. If you even show a sign of using the kids to influence her she will use that against you very fast! It is back to the detatchment issue again!
