WOW!! And more WOW after that. Morgan, this is a good thing. He didn't blame you at all, just expressed a fear that you won't ever trust him again. The rest was about him and how he feels about himself. I would leave the email for a bit, and decide what you want to do. Nothing wrong with waiting.
You can't help him get through this. I have tried to learn that myself. You can only do what you can do, keep his kids healthy and happy and take care of yourself. He is seeing now what he has become, and while its very sad, it seems a bit of a breakthrough on his part. He could have not responded at all. I wonder if email is easier because he doesn't have to look in your eyes, and can just type and get it out.
Of course you don't want him hurting, but you aren't pathetic. I can promise you that.
