Impulsive and self-destructive behavior is part of Bipolar symptoms, though not everyone goes through the same behaviors. Spending sprees, flagrant affairs or risky
investments can all signal bipolar disorder if they're out of character and part of a larger pattern of symptoms.
I would strongly suggest that your husband see his Dr. as there is help available for this disorder.
I would say your best friend is not the friend you thought she was.......................single therapy for you would be a good idea too, to help you learn how to heal from this.
