I, too, like Tam went thru a similar experience to what you are going thru - only I had no idea even tho I had a seperate checking account, retirement and vehicle that my now exAH would be entitled to half of ALL of it.
The legal system is not very friendly to spouses who try to support (emotionally or finanically) their mates thru addiction/recovery - when the spouse relapses and does keep up their end of the bargain.
They are still entitled to more than what you would imagine!! I walked away finciancially bankrupt - but emotional SANE & SAFE finally!
Please regardless if you are ready to leave or not - seek Legal Counsel to protect yourself - You at least should know the laws in your area to know what is best for you.
PINK HUGS & best wishes for you on your own recovery!!
