BarbieDoll, you already know the answer to your question:
maybe yes, maybe no, or somewhere in between or just another gopher wondering if spring has arrived yet (or what season is it anyway? what planet is this? Check for alien antenna sprouting next time you see him)
I can relate, x1 was same way, same speech at the D, "Not sure I want this" yeah yeah, so that's why she was trashing the finances and living with another guy.
Seems your x is looking for "control"anywhere he can find it, because it's probably lacking in his current state of life. Possible back steps to where he thinks had some control once upon a time and trying to regain, just to have some "control" somewhere, anywhere.

Don't do this to yourself and don't let him do it.

As you said, divorce does not bring closure. Instead, I submit, you do.
Hope you find it.
I'm still looking after x2 left. I finally found the closure with x1, but took a lot longer then five.
Best of luck.
Thanks for stopping in on MLC land.
