AND DONT TELL HER YOU ARE MOVING IN...take her parents with you and just WALK IN with your bags. Don't say a damn thing to her.
Someone should be able to house sit for you. Just make sure they never leave her alone if she tries to come by. If she gets someone shadowing her around the house she won't want to stay there no matter how angry she is.
I am not saying give up, I am saying change strategies.
