Bipolar disorder is episodic. No exceptions.
Bipolar disorder is an illness and is not about personality.
Bipolar disorder can be managed.
Without management, people with bipolar disorder have stable relationships and then chaotic relationships.
If you add substances such as cannabis marijuana or stimulants, the person will be in and out of bipolar episodes consistently.
Start with Loving Someone with Bipolar Disorder. It was the first book ever written for a partner of a person with bipolar disorder. It’s still the best in my opinion.
