Time for a new atty. I've never heard of EITHER ONE of these things (counting "net worth" instead of "income" in alimony and CS calculations, or pre-marriage jewelry being anything OTHER than sole property)!
And a good atty should be able to help you document a demonstrable case of "squandering of marital assets," that should come out of YOUR HUSBAND's side of the equation!
I haven't followed your sitch all that closely, MIL, but this doesn't sound right to me.
