Good for you! I, too, had some great times celebrating with kids and grandkids. I actually felt sad for XH that he was not there, but I have to remember it is his choice.
Now, if I can just get me back to 100%. I've just exhausted myself. I took time off this week to work on my house but so far I have done very little of the planned work. I have mostly slept and feel like I could sleep some more. But my thoughts are more toward getting the self-care I need for my thyroid problems and finding a doc who will listen to me and how I feel.
Glad you are doing well. Like you, I wonder sometimes how the WAS deals with loss and I think denial is the correct guess.
