Bipolar Partner

My husband had bipolar disorder, something that has presented itself more recently and it's had a huge affect on our relationship and my own development with my mental illness. We've brought up therapy and sometimes he's willing and sometimes he's not, but he clearly needs help and medication. I tried making an appointment for him but he had to work and a lot of the other doctors I speak to need him to make the actual appointment. Any advice on how to get a bipolar partner to go to a doctor and what to do when they're having an episode?
