Call me crazy, but I decided to invent a reason as to why her fate was tied to the ring. I thought, perhaps what was meant was that if the ring was not destroyed, Aragorn would have little chance of survival himself, and as she was holding on for him, she may not have been able to live with him dead. It sounds much less eloquent when I try putting in into words...but that's the gist.
