If she has her GC not much more you can do. If not follow the advice Crazy Cat posted above.
Good news is that she works, not likely to get anything from the affidavit of support.
I would move on, if you try to go after the money she made while married (yes some might try) it may backfire on you. Unless she racked up bill that should have been part of the divorce. Let her go and get that divorced finished.
