What the above poster said makes much sense to me.
You mentioned that your husband has good insurance at this time. Hopefully, the pain of what he has experienced or continues to experience would motivate him to at least be open to the idea of contiuing with medication and seeing a therapist for additional treatment. Bottom line...it's his choice to make, but more chance for real change with this type of treatment.

Additionally, if this causes you great anguish, I would agree it might be a good idea for you to see your own therapist.
