Nitty, just came over to check out your sitch and say thank you for your kind words on my thread. I am grateful for your compassion.
GAL, if, for no other reason, to save your own sanity. I am, and my WAW already filed (within 1.5 weeks of the BD). I will now ACT AS IF she is a neighbor whose house burned down and is sleeping on my couch. And may need a cookie.
However...with your deal. His pride seems to have taken over his logic circuits (worried you'll rub his nose in it if he changes his mind). And his family sounds like mine, agreeing with whomever happens to be in the room then reconvening to judge everyone involved.
A thought...I have had more fruitful (but still very sad) conversations with my WAW when I have said "Nobody gets to badmouth you around me. I won't condone it, and if one of my friends or family does so around the kids...they won't be seeing the kids anymore." I know that your children are older, but it still seems appropriate. Heck, defend him IN FRONT OF his or your family if such a situation arises. (Not sure if you two are still doing public appearances together.)
