I'm wondering why you have filed for divorce? It sounds like you don't really want one (since you miss your wife). The only good reason to file is if you are positive that you want to be divorced. Are you doing it to get her attention? My advice would be to slow down on filing. There's plenty of time for that.
It sounds like the 180s you are doing are doing a good job of that already.
How about making some goals?
Have you gotten some ideas of what she got from the EAs that was missing in your marriage? How can you start meeting those needs?
What can you expect? A roller coaster, so hold on tight. Soon your own ride will smooth out and her hills and valleys won't matter so much.
