BB, I'm definitely a proponent of "tough love" when it comes to waywards, and your W is about as wayward as they get. So I think you're doing the right thing refusing her advances. I have a feeling that some day this mess she's making is going to blow up and she's going to come crawling back to you, but it's going to be so far down the road that you will have more than likely moved on and want nothing to do with her. I understand your frustration and desire to just "rip the bandaid off" but I agree with LH, I wouldn't move out of the house just yet. You've got plenty of time, no need to rush things.
