Im sorry that you have been going through such a rough time..

Sure maybe shes shown some "Bipolar" traits from what you posted... Is Bipolar the reason she ended things? there is no way to hang her actions on "Bipolar". She could have other mental illness or maybe shes just a lousy partner even tho you had a good long term relationship.

People change, change mates, friends and interests I am sorry that your relationship didn't work out.

I understand your need to find answers.... keep working with your therapist.. Learn what you can from your relationship with her and then move towards having a future that your enjoying and thriving in.

You deserve happiness don't get bogged down in the past for too long
