Hey jules, okay I found that odd too...I worked in mental health for many, many years. If someone has the symptoms of BP then it is very likely they have BP...but symptoms of this can be eased with the proper medication and treatment.
As for your husband I would find that very uncomfortable too. Have you called his doctor on it? Are you sure he is taking his medication as prescribed? It could be a sign of worsening psychosis so I would talk to the doctor and see if a med change is in order or an adjustment perhaps before it gets out of hand.
Please let us know how it goes...My thoughts are with you..take care
