I have mixed feelings about the Christmas get together. I did Thanksgiving lunch, and it was soooo awkward. I just told him when he left..."Thanks for coming. I won't invite you again."
If you can do it without the rest of his family...just you guys and the kids, that might be okay. It's really about what's best for you and the kids right now. What you can handle emotionally.
On the email notes...when he decided he didn't want to be married to you, he gave up the right to know what you are doing, thinking, planning, etc. So, you don't owe him that any longer. He needs to begin to see what D looks like. It doesn't look like you being concerned about his reactions to your emails etc. Just keep that in mind as you prepare to respond next time. How much information do you really need to give? So what, if he thinks your tone is not friendly, etc.? It's hard to draw the line...I know. I still struggle with it. But, I'm working on it. And, I'll point it out to you too just because it's easier for me to see in your sitch than it is for you!
Hope your little one gets better quickly.
Hugs to you! Amy
