LH, You might want to try the notebook approach. My spouse and I did a Marriage Encounter weekend last fall and the neat thing we got out of that was using notebooks to write answers to relationship questions and then read the others answer and then talk about it. You also might want to find a list of emotion words, as one is working on being a re-formed Vulcan in terms of emotion, that might help him.
He also may be reluctant to talk as "relationship talks" in my house used to be a list of things that I was doing wrong and therefore causing the problems. It was this approach that would make me reluctant to want to do those talks.
Just a couple of things.
