I kind of want to say "What they said" to all the posts above.
18 months ago, I left a narcissist abusive porn addicted gambling alcoholic husband of 20 years. I was gas lighted and a victim of Stockholm syndrome -where your abuser isolates you and gradually convinces you that you can't live unless he controls your life...
I made it out. One of my posts is in the sticky "What is Abuse?" on the Friends and Families of Alcoholics forum here at SoberRecovery. (A "sticky" is a post of universal interest that is permanently kept at the top of the forum page.) There is a lot going on the F&F of Alcoholics forum right now that would be useful for you to read. You can post and read here at SoberRecovery (SR) on any forum. For those of us involved with addicts, it often doesn't matter which addiction they have - alcohol or drugs or others - we suffer similar consequences, and our solutions help each other.
You can do this. You can get free and be healthy and happy again.
All the posts here are helpful. Having lived with and divorced a narcissistic alcoholic, I think English Garden is spot on about divorcing a narcissistic spouse. Aside from just trying to separate assets, they want to WIN, and to them, they win when someone else loses. The bigger the other guy loses, the better they win in their minds.
So, I agree that if you have joint cash or liquid assets, take half of them and put them in your name. There is a thread on F&F of Alcoholics about "I think I'm ready" by Jarp and it has lots of good advice about what to do when you need to leave a nasty spouse.
Good luck, keep coming back!
