I am so sorry you are having a tough day. It's ok to, you know. This is all very sad. So, have a good cry. One day, when you can, those feelings will wash over you.
It's also ok to treasure your memories, S. They are part of your life story. They happened. They were real.
They do remember, Shining. They just cant feel that right now.
There is no way of knowing if he will do what he needs to do. I dont know why some do and some dont.
But there is always hope.
You are going to have ups and downs. This doesnt go in a straight line. It all happens as it should. You just have to believe that.
