You can file for divorce without her consent. If you want to file for divorce, you will have to be present for any associated court hearings. In an uncontested or default case with no children, it may be possible to do that with a single hearing; but court practices vary by state and also by local rule so I can't guarantee that. If you retain a lawyer and the divorce is not contested I expect you will be able to avoid any hearings prior to the hearing for entry of a judgment.
