Here's my suggestion. If you can hold off another weekend, do so. Tell her you are itemizing what she can have an writing it down for the L. Even if you don't have one, take charge and just mention that.
After you've written your list, send it to her. If she approves, take those items, put them into boxes and have them waiting for her outside of the home so things don't mysteriously "walk away". Right now, you need to show that you are in control and she's not the one who has your balls in her pocket right now.
It's okay to keep things light and friendly, but for the possessions, business is business.
Or if you do intend to have them come into your home, remove all pictures of you and your wife from the home. Show that you're not concerned anymore. In fact, it would help if you were in the middle of painting your Master Bedroom as they come in.
She may be proud of having a place of her own, but so do you.
