Hey Jim, I'm sorry your W is doing this to you. I agree with Ginger - she's messing with you.
Regardless of what your W's motivation may be, these episodes are not healthy FOR YOU. It's like she's actively trying to disrupt your GAL. She's showing up, looking her best, and almost making a spectacle of herself. She might as well wear neon lights and sparklers.
Is ignoring her an option? What about simply leaving? I know it's "your" place, but if she's making it so awkward for you, it's not really "yours" any more.
