When W says something like "I don't love you and I want to be divirced as soon as possible", How do I even start to turn that around? Do I just smile and be happy go lucky? What would I even say? How would I even respond?
How about... "I have come to understand how you feel that way. It makes me sad to think my words and actions have fostered those feelings in you.".
Certain words do not reflect validation of opinions and/or feelings, IMO... Could, might... eg... "I understand how you might feel that way" or "I understand how you could feel that way".
"because deep down I feel that she just wants us to hate each other..."
Quit assuming this... Stop. Desist. Seriously.
Thoughts become words which become actions which become habits... Negative thoughts become part of your aura. People can sense it.
