Get thy self to a good attorney.

Best to get a lawyer involved now. Talk to a few of the best in your area. That will prevent her from using them herself.
Get all documents out of the house, or copied. Deed, birth certificates, passports…..all of it. Tax returns, bank statements. Take copies of her documents as well. Never know what is lerking out there.

Also, buy a voice activated recorder in case she gets crazy. She will try to have a restraining order if you decide for financial reasons to stay. It’s in the woman’s divorce handbook. Lesson 101. Domestic violence is not looked at kindly in this matters and it is so easy for a woman to cry wolf.

I’ll be praying for you brother
