GC-
Well done!
I want to point out one thing here, that I hope you can cling to in the weeks to come. Before the meeting you said this:
I'm not as upbeat as yesterday - torn up from thinking she's living it up without me and considers us done -
Now that you have seen her, and realize that she has become too thin, she was crying, there were cracks in her armor, and she does not seem at all happy, I want you to remember this picture of her the next time she becomes cold and hard to you.
A phrase that comes to mind a lot for me these days:
things are not always what they seem.
The WS parades around town with their new person, acting like nothing is wrong. They say they are "happier than they have ever been in their life". But - inside, it is a differnt story. Loss of stabilty. Nothing is familiar anymore. The other person seemed so passionate, and romantic. In reality the other person is actually into drama - of any kind. If life isn't dramatic enough for them they start stirring stuff up.
In my own experience - any time my WH and I would ahve a truly good talk - it would be followed by something really awful within the next few days. I think that when the WS occasionally peeks out through the fog, and remembers what was good in their relationship with you, they go back to the OP and they are suddenly questioning their choices. So the OP strikes out in an effort to keep them in the fog. The OP reminds them of every reason they had for leaving. "remember, he didn't love you like I do, he wasn't as romantic, he left his socks on the floor that one time....etc.."
Do not be surprised if you hear from her within the next week and she seems even more determined to file. Don't panic. It is just part of the script. Just keep reminding her that you do not want the D and will not help her file.
Just because they threaten to file soon, or tomorrow, doesn't really mean it will happen.
You are doing a great job. Please let yourself feel upbeat this weekend. It is ok to have hope.
