Do you have an attorney? If so, please take this question to the person who is handling your case.
That said, the general rule is 50/50 on property and debts. I like to use the analogy that you are playing with poker chips and until the decree is signed, you do not have to settle up. The end result is supposed to be "fair" and you can ask the court to award more debt to him because it is fair, or because he is taking the asset associated with that debt, or that he took the benefit of that debt, etc.
