I agree with the poster that said start over with a new doc, and when you make the appt, get agreement that both of you will attend the first session. Tell them you want to give your observations for a few minutes and then you can leave and the doc can do the normal eval with your husband. If they don't agree to that up front, then don't go.
It would also help if you brought a 1-2 pager with your recent (last 6-8 weeks) observations and his med history, in a timeline format. That way the doc can refer to it when you leave the room.
When you get to the appt, your husband will need to sign the HIPPA release. I'd also suggest you tell the doctor your husband can't reliably describe his symptoms and is in a crisis state such that he can't advocate for himself (make appts, be proactive, etc), so you want the doc's agreement that you can call anytime with updates, and the doc can follow up by talking to your husband, or having your husband come in for an appt. That's the key thing -- the doc needs to verify with your husband. The doc can't just rely on your observations - that's dangerous territory for them.
I have a mentally ill brother, and my mom has often taken the 1-2 pager. While my brother won't sign a release, we have found that the docs will often listen to my parents' observations, e.g., one way communication, because my brother is very non-compliant and has schizophrenia, so they get that they need the family input.
I am also not convinced that your husband is so ill that he can't advocate for himself -- it sounds like he just doesn't want to. And it sounds like his behavior, while impossible for you, is not so severe for him. In other words, he doesn't feel bad enough to want help, while you are tearing your hair out. If that's the case, then I think you are in ultimatum territory -- i.e., you get help or I leave -- or something along those lines. But ultimately, getting help is his decision. You can't make him.
Also, the advice from the PP on 10/11/13 at 10:27 was spot on -- pay attention to that too.
