Does your wife understand bipolar disorder? It might help to start there. Mickey's suggestion to take her to an appointment is a great one. Seeing a therapist together can also help. Additionally, I read a good book that has sections specifically designed to assist family members. It is called 'Take Charge of Bipolar Disorder'. It helped me learn more and also helped me learn how to work with family and friends. Likewise, it was a good resource for family and friends to learn on their own.

I think anything you might have to share about your behavior could be helped by her knowing how bipolar affects the brain and why it is not easy for you to control the behavior. It might be helpful for her to understand that altered sexual behavior is a common symptom of mania and that you're not using mania as an excuse to engage in behavior that dishonors your marriage.

I think it is great you are coonsidering telling her and asking her to help support you to hopefully keep you from doing things you wouldn't want to otherwise. I have a family member who had episodes and I desperately wanted her to share with me what was going on and to tell me how I could help. She shut me out completely and we did not speak for a long time. She made no apologies for her behavior and didn't take steps to manage it. I felt helpless. I decided when I got sick that I would include my husband in creating the strategies to manage my issues as well as making him a part of the plan. I think that helped him to accept my illness, but also made him feel less helpless.

You can do this, and I'm wishing you all the best.
