I am not sure about that, I know many people who divorced then remarried. I would just not personally be in a hurry to sign anything. If she files, find out how long those papers can languish before you end up divorced by default. Or whatever the proper legal thing is in your state.
You might need to see a lawyer to get yourself informed, if she has already started paperwork.
Hopefully some of the more informed folks will weigh in on this!
