I came to a similar realization back in Dec/Jan. I was hell-bent on filing for D. Then someone on these boards gave me the advice that I should only take that step if that is what I truly wanted (a D) and not in reaction to her actions or non-actions.
I thought about it, and I transitioned to a neutral state. Now, if she continued the EA and didn't move out I am not sure what I would have done, but even now that she is moving out I am still not going to file for D for now. I figured I would know when the timing is right.
I am still waiting for that moment.
