I make much more than my spouse does, but my spouse will be getting a million dollars’ worth of property in the divorce. Will I still have to pay spousal maintenance?

You might. Certainly, you will have an argument that your spouse has enough property to be self-sufficient such that spousal maintenance should not be ordered or should be reduced. But the Court will also look at whether spousal maintenance is necessary to help the receiving spouse maintain the lifestyle established during the marriage.
