Another mother asked me why stbx wasn't there to watch his son in his moment of glory.
I told her he was gone. She was incredulous, as she'd known us since our two sons were in kindergarden together - the old "He was the last person in the world I thought would ever do that!"
Don't know if this makes me feel better or worse about my sitch. At first I thought - Wow, I'm right; there really is something wrong with stbx. Now, I just feel like it sorta adds to the tragedy and unreality of it all.
