Oh, a lawyer? I'm sorry...lol...my sister and her H are lawyers so I know the drill.
I use a lot of questions that keep them talking, like "tell me more about that", "How does that work for you", etc.
Also, when I am questioned on my silence, I say "I am just listening to you so that I understand better" sort of things.
And of course the standard issue: "I'm sorry you feel that way"...
The biggest/hardest thing for me was to learn how to not think of my responses while W was talking, to not think of ANYthing about me or my thoughts/feelings and focus 150% on her and what she is saying.
