Wuz, I am sorry that you are having to go through this. I can relate - from the other side... kinda...
I had been married to the now ex (Jw wifey) for about 20 years when I told her that I wanted a divorce. She didn't seem too surprised (perhaps that should've been a clue).
I moved out, filed for divorce, which was later granted. She kept trying to get me to admit to her any infraction that she could use to claim her 'freedom to remarry'. I told her that the courts said we were divorced, and that should be good enuf for her.
Well, she got remarried within the year to a fella that I suspect she had met at one of her conventions. Them there conventions ARE useful for some things, eh? Even when you're married... you can meet your next mate (especially if you're married to an unbeliever).
Be sure to get you a good lawyer. Tell them all that has occured to lead up to this moment. Lawyers know how to work the court system. If you get a good lawyer, they'll make sure that you come out of this okay.
Regards,
Jim TX
