It is so hard, isn't it? You can either not respond and take your time or you can just get it over with asap. Whatever will bring you the most comfort. If you are, definitely stop worrying about him and how your actions will influence him. Do what will work for you. I sort of like the suggestion of using a third party, like a mediator. Good luck and feel better. I've had a horrible day, so I'm going to steal your journaling idea and start doing it myself. Good night to you in Georgia.
