It sounds like he really needs to see a pdoc and possibly couples therapy for your marriage. It does not sound healthy at this time.

Hyper sexuality does occur with some people that have bp. That is not an excuse as we are all responsible for our actions. I have never never not known what I have done but that does not mean that it is not a symptom for him.

I am sorry you are having to go through this. You need to take care of yourself too. Maybe seeing a therapist yourself can help you sort through your feelings and needs. I hope things improve for you. Take care.
