Just accept that he is gone and it will be easier to move forward and do the things you need to do to heal, learn, grow and detach.
Sorry though, I know that feeling. It stinks big time but you are also overthinking it. Every WAS starts toacts different in some ways.
You are right, I need to realize that he is gone. A part of me wants to save him, but I have to let him fail on his own. To not be there and help him out.
