lol, seriously, what are you talking about?
You cannot be serious with this nonsense. You can leave her behind a couple of times but then she will be driven mad by voices in her head to attack your party...if you then say you let her stay the voices instantly stop and she collapses on the floor unconscious, asleep. If you refuse she will attack and force you to kill her. That is by design and again by the rules of the DM. Please go back and read the bloody thread.
