Yes.
Nothing you've done so far has helped, so why not try something new?
After all of your sacrifice, all of the drama, all of the hurt your husband lives with, ask yourself what kind of life you deserve.
It's the hardest thing I ever did. It didn't change her choices, but it removed the chaos from my life. It did make her lash out more viciously as I tore our symbiotic relationship apart, but she has always found a place to lay her head.
The guilt never goes away. The love never leaves.
My heart breaks for you.
