You need to be aware of the possibility that she may think you are wanting to hide money for what ever reason.
What I used to do with the Ex was both put everything into one account, paid the bills and then each transferred the difference from our input to 1/2 the bills and total put in to our own savings accounts leaving $100 ($50 each)i n for clerical errors. Gas for my car,lunches, ect that were my personal expenses came out of my savings and same for her.
My only concern was that the bills be paid first before anything else. Neither of us ever had any problems with that. There was only one check book for bills, and We paid them all online.
Everyone knew what money was there at the get go. The bills were paid and both were in on all steps.
We never fought about money.

Cheers
Doug
