Great you are feeling better about the situation; yet, I think it still would be prudent to be taking some action on this. Be proactive.

Support groups are great for all sides on the matter. Many communities have support groups for just this sort of thing; meetings for family and support persons of those with mood disorders or other mental health concerns. Also, it could be good for you and your son to attend your own. Some of these groups will welcome the attendance of a support person. The group in another city I lived in did so and I could tell it was of great benefit for it changed the perspective of the loved one by seeing that there are people who have been having a success at some level of recovery and living with their illness. So too I would check with your community mental health organisations for resources available for your husband. He need not feel alone dealing with this. He need not be alone in not completely understanding this either.
