If you love her, you can stand beside her as she gets the help she needs. Turning your back on a sick person is only something I would suggest if you no longer care about her or she's pulling you under the current with her. People with this disease die out there on the streets. We make poor decisions which can kill us and get others in dangerous places. You must strengthen your own resolves so you can be support to her (if that is what you want). She needs people who will stand by her through it all. Some high functioning bipolar a do okay alone, but most need a very strong support system which doesn't up and leave when times get tough.
