tjp offers some sound suggestions ~
It is painful to finally have to walk away from your marriage but if this is what you have decided you are going to do, I agree with the suggestion to seek legal council about what is the best way to protect yourself legally and financially.
Often we believe that because we have stayed for many years, thru the relapses, thru the illnesses, thru the DUI's, thru the community service, thru the unemployed years, on and on and on ~ that our mates will be grateful for our "time served" and willingly allow us to move on and wish us well. That they will gladly give us our fair share. This is not usally the case.
If you read many of the post here - it gets ugly, mean and spiteful. And the court system has no laws to help the spouse of an alcoholic/addict!
I wish you the very best ~ a life with peace, joy, laughter, safety and sanity!
PINK HUGS,
