There is no doubt that you love your girlfriend. And I think grizmom gave you some good ideas. Always remember that she is not going to get treatment unless she wants it. Sometimes the tough love approach like grizmom said, is the best thing for that individual. It doesnt mean it is easy for you.... but living with bipolar isnt easy for her.

If you do opt for the tough love, please make sure that you at least keep an eye on her. That approach may cause a downward spiral. If you and her have mutual friends... who know about her bipolar, you may also give them a heads up before a tough love session, so that they can help keep an eye on her while you take care of yourself.

Good Luck in whatever your decision is and come back when you can
