Ex refuses to sign Texas final divorce decree. How long can she delay the divorce? Can it be finalized without her signature?

After two years of trying to get divorced, with my ex fighting every move, we finally came to an agreement and signed a Rule 11. As soon as we signed it, we went before the judge and I answered lots of questions. My attorney then asked my ex if she had heard all the questions and if she agreed with my answers. The judge then said he would grant the divorce and gave us an entry date. Later, when I got a copy of the Final Decree, I signed it and gave it back to my attorney. The entry date came and went. I found out that my ex refused to sign it. She wants changes made on things SHE asked for in mediation. We refuse to make changes. I’m hoping we can complete this without her if possible. The decree has spaces for my signature, my ex's signature, both attorneys, and the judge.
