First, to be clear, marrying does not necessarily mean you pay less tuition, it will just make you independent for filing FAFSA. So you would be eligible for a Pell Grant if your income allows it and you can borrow at the Independent student limit which is 4k more than dependent students.
Are you already enrolled at Davis now?
I do not think you will be reclassified as instate just by marrying a non CA student.
Are you self supporting?
