I am not one to encourage mindreading...I am a recovering mindreader, as you probably realize by now, but you really seem to be struggling with what all of this means so I am going to give you an alternative. Not because I think this is a good thing to do, rather, because I hope it will show you (and me for that matter)that there are always so many possible explanations for actions taken by others that guessing is futile. Here goes:
I am an attorney and while I do not practice domestic law, I am a litigator and I will tell you that missing a deadline in our business is among the worst mistakes an attorney can make. It is entirely possible that your wife's attorney contacted her, reminded her of the impending deadline, sent her an affidavit to sign and then filed it. It may mean nothing more than that.
I do not like contributing to analyzing the reasons behind the actions of others. I really have no better idea of why your wife did what she did than you have. I did this because you are doing so well in staying focused on yourself and I do not want to see you get derailed. Hold on to all you have accomplished and keep it up. I know all about these moments you are facing and how very hard they can be to get through.
It's okay to break down and cry. In fact, it's good...feel those feelings and then refocus and get back in the moment. By thinking and overthinking about the motivations of another, all we really do is breathe life into our own fear. In these moments, I like to read and reread that article that Carlos added to your thread as a link. It provides me a lot of peace.
Trust that you will be okay no matter what and you will.
