You can take a deep breath and step back. Keep working on yourself and continue with your changes, regardless of what she does. You pressuring her right now will not help at all.
(In the U.S anyway) Those online filing services don't actually file the paperwork for you, they just prepare the paperwork and you submit it to the courts.(Don't quote me, just my experience) So she will likely need to pay both the service and the court to file. For my W, that online service took nearly 2 months to prepare the paperwork and even then they messed it up to the point the court house rejected it when she tried to file. Not hard to realize when the child care plan only lists one of our two children. She ended up paying the service nearly $300 for nothing.
Even if the service prepared the paperwork quickly for her there's generally minimum waiting periods (6 months in my state) before a judgement of D can be entered. They do this when there are minor children in the household, for their own well being.
Time, you still have that gift. Continue to work on yourself, but don't be in denial about whats happening either. Anythings possible.
Accept what is, let go of what was, and have faith in what will be
