I read your past posts. in them you state he does not know he dissociates and will not go for diagnostics...

Im sorry but theres nothing you can do for him. Just like the tools of alcoholics Anonymous teaches about living with an alcoholic, Only the person with the problem can do anything about the problem. He is the only one that can use the tools that help people with dissociative disorders like medication changes, getting enough rest, nutrition, fluids, go to therapy, learn how to ground himself. Only he can make it so that he doesnt dissociate any more.

thats not saying you cant do your part in this equation of being someone who has mentally ill loved one..

you can enter therapy yourself to learn how to take care of yourself and your problems / emotions with having a loved one who is mentally ill.

my suggestion contact a treatment provider in your location, at the very least they can help you understand and take care of your own problems and emotions that you may have surrounding the fact that your husband is mentally ill and will not get diagnosed /treatment for it.

by the way I am the spouse with mental disorders and part of the reason my wife is in therapy is because i have dissociative disorders. Being in therapy herself has helped her to see no one but me can fix/ help me with my dissociative issues, it has also helped her to have someone she could talk to about the many issues that arise for her because of my having dissociative disorders.
