What do you think about opening a separate bank account?
If you can't remove your name entirely from your joint one due to household expenses being paid from it, if you have DD, you can at least stop that and open your own account and then deposit whatever you need to in the joint one to pay those bills.
If you don't have DD, just open a separate bank account on your own anyway.
I think it makes a statement, without being harmful to your goal.
