Your wife is looking for validation and affirmation from the family on how she has moved on and decorated her new home. She's bragging in her own way. It doesn't matter that she can't fit everyone in the home for Thanksgiving because she's not thought that part out completely.
Enjoy your holiday w/your children. She's going to have a lot of questions tossed her way from her family, etc. It shall be a very interesting holiday!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
