Birthday party was good. Kids had an absolute blast.
Wife was moping around and we didn't even speak. I remained upbeat. I got dirty looks from her as I talked and laughed with her family. She left for about 20 minutes, pretty sure she was crying. We both kept to a small group of friends. It was weird at first but I got used to it. The most important thing is the kids seemed not to notice the hostility.
As we left, I got no acknowledgement from W. Her family was very grateful.
