True, given enough time she MIGHT decide to stay. However, she might not. And what if she decides that she is bored again in 6 months? How much are you willing to tolerate?

Forcing her to make a decision might scare her into getting her sh*t together while reinforcing the idea that you have backbone, dignity, and certain justifiable expectations for her behavior. She might not stay, but you would still have your backbone and dignity.
