I am so sorry to hear of all that you have gone through and continue to go through. It's really not fair.
My only words of wisdom for you is that you have to trust that you have done all you can. You should be commended for sticking through all this. He is the one that will have to seek out help and I can tell you that men are very resistant to therapy or help of any kind. They are taught from childhood not to be vulnerable. Pretty sad if you ask me.
I understand your feelings from a different perspective. My H is going through an MLC and has filed for D. I will move on but never give up.
One day, he will figure it all out, get well and come knocking on your door. At that juncture, you will have to see if you are still willing to open that door again.
Stay Strong!
