Personally I felt I needed a third party to listen and observe, hence why I (we) contacted you. That is where the sessions were so useful, especially my solo session, after our first one together. The joint sessions were more offloading, but they highlighted where our problems were, much of which were just stubborn refusals to see each other's point of view and understand how to react when there was an argument or fight.
Speaking openly and honestly in an environment where we could, and knowing we wouldn't hate each other afterwards, really helped. It was an hour to offload in front of a professional who highlighted points that helped make us aware of where our issues were, and where they might be resolved. (G)
