Ghost, it pains me to see you still stuck in the same cycles as you were before. It must be hell and I cant imagine how you are able to stay in that place. I know in house separation makes it very difficult to do what you need to do but you need to do something.
You have to decide, decide to move forward and live your life. You can give yourself permission to give up on saving your M.
Accept what is, let go of what was, and have faith in what will be
