I totally understand, you are not alone in feeling so out of control. Pain equals change. He has to feel the loss to make the changes. I was with my ex forever also. You have to take one day at a time to get through the fear. I was terrified. I remember shaking in my bed before I went to sleep and when I would arise. It is a living nightmare, but you have to find a way to cope and move on.
