I think it's because we are in such disbelief that the person we once knew is doing crazy and hurtful things.
My story is different than yours. My STBXW has left me and our D's. Triple whammy. Plus this is my 2nd BD from her . First one was about 10years ago.
All in all I'm not hateful or angry towards her. I'm saddened that she dies what she does to the D's mostly.
Hopefully your H wakes up one day. So many life events he will miss if he doesn't
Hugs Irish
