I think the fact that she remains committed to you answers the question for you. She clearly needs to become educated about Bipolar, however, you need to understand the pain that bipolar causes significant others and if you are healthy, prove to her that this vicious cycle has finally ended and with her support you two can be the couple you were always meant to be.
While your actions during your manic and or depressive episodes were likely a direct result of your untreated bipolar, it still hurts and it still diminishes trust in relationships and many secondary issues., it takes time to process and get over.
If you love her, make it work, you stay healthy and help her process through the way she helped you....
