Divorce is not about being fair. It's about business and who gets the better deal.
Itemize the items she wants and assign them a value. Since you are married they are part of the marital assets that will be split 50/50. I hope you have a list of items that she has taken already. If not draw up a list and include these latest items. Ask her to sign the paper that she acknowledges possession of these items and their value will be taken out of her part of the D settlement.
Better yet, reply that you are not comfortable parting with any possessions until the D is finalized.
