OH NOOOOO

I'm so sorry to hear that

I was kinda hoping that you were just busy with life and your 2 little ones and not having serious problems. I was also kinda hoping to meet up with you once in Vancouver

As far as getting a divorce goes, you need to do it under the laws of your own state but it is not necessary to present Vienna with a finalized divorce in order to cancel the procedure and withdraw the application.
For what is worth, I hope that divorce would be your last resort and you can work thing out but if you're already passed that stage, I truly wish you good luck and success where ever you are
