You're interfering with her fantasy of buying all new stuff for her apartment. How dare you suggest she take some of the old stuff!
Now, I don't recall your financial situation, but don't hesitate to consult an attorney. A fair deal would be dividing possessions and assets, then new stuff that each of you buy is your own individual expense. What wouldn't be fair is for joint funds to be used towards buying her nice new stuff while you get the old stuff - unless that's what you wanted.
