Can you block her number? Or, set a silent ringtone when she calls. Something, so that you don't have to deal with it. I know. It hurts every time they call. Everything comes back up again and it rakes your emotions through the crud. I'm really sorry that you have to deal with this and that she is playing with your heart like this.
I would honestly change your locks. That way, she can't get in to, as you say, "rape your house." That actually is a very good way to describe what she is doing to you. You've got to stand up and take control of this.
Get her things out of your house. If there is nothing there and she doesn't believe you? Well, that's her problem. At this moment, when she comes into your house without being invited, she is breaking and entering and can be charged. Hopefully, it doesn't come to that point, but it may. I would make sure she knows that you are no longer going to put up with this.
Find a way to tell her that she is not welcome in your house and that you will take necessary action if she does come in. Then do it. Follow up - don't give empty threats. Figure out what steps you're willing to take to get rid of this and stick to it.
