Hey Chris! I just want to echo what others have already said. You handled yourself really well in that convo. I wouldn't worry about showing a bit of anger. You're a human being with complex emotions and you showed her something authentic. It may not register for her right now, but she will realize how she has hurt you and you not shoving that on the side is good.
She is clearly trying to manipulate you and get you to do the papers so that she can tell the world that you wanted it. If you're not ready for filing yourself, then let her do all the work.
Also, you don't have to get the papers in person. Tell her to mail them or drop them off in the mailbox or whatever. I feel that her trying to see you in-person is just a way of her to get her temp check.
At this point though, just go absolute NC and dark. Block her if you need to. This is not going to have an effect on your chances of recon. We know that people who have gone through divorce seen the WW come back years later wanting to recon. I know the timeline is ridiculous and daunting, but if you keep your focus on recon, you're going to miss out on life.
As we say here, your MR is dead. Just say the eulogy and move forward with your life. She hasn't shown through her actions or even a drop of remorse that she wants to recon. Just let her be and gain your sanity back.
