If she didn't have the money for a L, I wonder what her motivation for asking for a few months would then be. She wants the D now, she knows you don't. Maybe time to figure out another plan to get what she wants financially? Hard to tell
I just get the impression its not all about wanting to scam you, but I could be wrong. To me I think she knows she messed up with not working with the mediator at first and lost some control when you got the L, now shes wanting to get some control back. She does keep mentioning control/calling all the shots, and I can see where she might feel that way in some circumstances even if its unfair to you and her own doing.
Accept what is, let go of what was, and have faith in what will be
