+1.
My MIL is now dead but I can't imagine having to deal with this.
I would absolutely start a box in the garage and every time some knick knack or throw rug shows up, quietly take it to the box. If MIL asks, let her know that they aren't your style so you are putting her things in storage so they're ready to go when she signs her new lease.
Is there a way to get ahead of her on the cooking each day? Start things in the slow cooker, or thank her for spending the afternoon making X, that will make great leftovers for lunch tomorrow but tonight's menu is Y. Post the weekly menu on the refrigerator and grocery shop on the weekends.
From there it's an issue with your husband. You should not agree to move another person into your household without a spousal discussion and understanding of what that looks like. Did he and his mother agree without you that this would be a long-term arrangement?
