Thanks everyone for your kind words and support. I never really looked at it like spiritual endangerment as a few have suggested. I've managed to stay relatively niaeve about it all during our 10 years together as I simply think it is along with all other religions a bunch of fairy tales. Shes always largely hidden it from me aswell... by that I mean there is no thanks given at my table... well as long as I'm there anyway.
The reason I felt I should ask her as it was me that gave up my last name so to speak to allow her back in. Very brief explanation... we were young she was rebelling, she got pregnant, she got defellowshipped, no friends, no family, no support = miserable... didnt want my baby mama to feel like that so went and signed a marriage certificate... no wedding at all. So I gave it up for her and made that sacrifice I wanted to know if she would return the favor. But it could potentially save our marriage aswell, I feel like the main reason I want out is were not even friends anymore and haven't been for a long time and the jw thing is a major reason why... we just see the world so differently.
As for having my legal ducks in a row, I should be fine really (just fyi were from the south Pacific), I dont want to take custody but have a shared arrangement, and as we are and were a young family of 5 we never really gained much financially so theres nothing really there to split as in property etc. I'm hoping to keep things amicable moving forward so we can sort most of this situation without lawyers and the courts involvement... but time will tell on that one.
