Tinker- I really admire you for your efforts in supporting your husband. The best thing (in my opinion) is to really help your husband learn how to recognize his mood cycles. It's a skill that takes a while. Sometimes just saying, "I know you say you are feeling good- but you've been pacing which makes me think you have something on your mind. If you can't talk about it now- I understand- lets try to talk about it when you're ready."
