John,
I think I would totally leave her alone. If she asks I would say that you don't have time to be bothered by somebody who isn't interested in you.
I think she is trying to get you to kick her out.
That way she can say to the kids, "See he kicked me out. I came back and he kicked me out."

I'm really sorry if I sound mean! I really don't want to make you feel bad. She just doesn't sound to me like she's trying. It seems like she may be playing games again. Mind you, I could be dead wrong.
