Whenever I felt at an impasse with my T I knew I had other issues so I'd pick a different one and work on that for awhile. I found over the years that most things are "connected" so working on something else would often free up another piece of whatever it was I was stuck on before.

I would make the next appointment with your T and begin the session by pointing out that you seem to be stuck for the moment and would like to work in another corner; that you're a complex enough person that there are other pieces of your puzzle you can work on and you promise you'll come back to the tell-the-husband issue later. It's your therapy; he should not push so hard as to go over that boundary. You get to work on your choice of what to work on. If he "refuses" then he is probably not a good T for you. He "should" give in gracefully and be able to turn his attention to something else; decide now before the next session what you want that something else to be :-)
