I would want to go back to the L and ask her the following questions:
1) When will the order go into effect? 2) What are your options legally? 3) What would you advise me to do while I stay in the same house as W? Not interacting with her?
We cannot advise you as it is a legal matter and I think your L would be the best person to answer your questions.
If I were you, I would not be in the same room as W is in the house. If she tries to bait you, tell her calmly, "I am very deeply saddened and hurt by your recent actions and I have no desire to have adversarial interactions with you. I have zero interest in it. Please leave the room."
I'd wait until you after you've received advice from L and ask her what you should say to W in the event this sort of thing comes up in the house.
